This script has been widely available to read on the internet for many years, so I won't go into detail about it. I will say that as far as detailed origin movies go, the Mankiewicz script is much better than the slumber inducing Batman Begins (no jeers from the Nolan Kool-Aid drinkers, please). All it needed was to be slightly revised to include some of the better Burton-Hickson ideas I will give in detail in a moment, so that Batman wasn't such a public figure (he would give televised press conferences), and perhaps a few other tweaks (the way Batman kills Thorne in the finale with a giant thumbtack is almost laughable... Burton's reworking of the finale is much better), but otherwise it was great. Faithful to the comics, good character development, great action scenes (perhaps the best is the Penguin scene where he and his goons are wearing jet pack umbrellas, going after the Batmobile, which during the course of the scene transforms into a speed boat and a jet), epic, and fun. Fun, but also has moments being quite dark, such as the ending where Silver dies in Batman's arms. (It could be argued the Mankiewicz script was also the basis for Lee and Janet Batchler's script for Batman Forever. Both scripts share many of the same plot points, and the Dick Grayson scenes are lifted almost verbatim from the Mankiewicz draft.)
Needless to say, pre-production stalled. Jon Peters and Peter Guber were brought in as new producers by the mid-1980s. Melniker and Uslan, while retaining an "Executive Producers" credit, had no input, creative or otherwise, on any Batman project from that point on. Guber and Peters brought in Tim Burton, who with Julie Hickson, wrote a treatment that attempted to "Burton-ize" the Mankeiwicz script, while adding the distinct flavor of the 1940s era Batman comics. The basic narrative of the Mankiewicz draft remains, but Burton and Hickson add their own touches to it. Both drafts establish a political showdown between Thomas Wayne and Rupert Thorne. The Joker in Mankiewicz's script is Rupert Thorne's hired gun, and is portrayed as a murderous stand-up comedian, while Thorne is the script's dominant villain. In the Burton-Hickson treatment, the Joker is much more insane, and answers to no one. Although initially hired by Thorne, who is more of a minor character here, to kill the Waynes (in the Mankiewicz draft, the Joker has Joe Chill be the gunman and then kills him afterwards), Joker turns on Thorne and kills him at a mayoral debate.
Burton reworks the origin sequence to resemble Detective Comics #235, where the Wayne family attend a costume after-party following a performance of the opera Die Fledermaus. Thomas wears a "majestic bat costume," while Martha is a "delicately shimmering fairy queen" and young Bruce is a "small whirling harlequin." The Joker, described as a 17-year-old boy with "shock-white skin, radioactive-green hair, standing on end as if permanently electrified, and red, red, lips slashed into a chin so pointed it’s like a demented exaggeration of a clown face", kills Thomas and Martha from an ice cream truck as "insipid tinkling style music" plays. Alfred vows to Bruce that "as long as I live, you will never be alone." Commissioner Gordon's role was more pivotal in this treatment, being a surrogate father figure to Bruce, and suspecting he is Batman, but doesn't confront him about it. The Batcave also derives from the 1940s comics by having the entrance be a “nearby barn located several hundred yards from the mansion which has been connected to the Batcave by an underground tunnel.”
Where the Mankiewicz script dwells on Batman taking on various street criminals, Burton focuses on The Joker's reign of terror consisting of releasing animals from the zoo, preempting TV broadcasts (he holds Barbara Walters at gunpoint as he forces her to interview him, and he preempts himself into The Love Boat with guest stars Tom Bosley, Cloris Leachman, and Andy Warhol), painting all the windows of Gotham's skyscrapers black, making the subways run backwards, and painting the entire city candy-striped colors. Bruce saves Silver St. Cloud at one of the Joker's crime scenes and starts a romance with her. The Joker then mock-elects himself mayor after killing Thorne and Bruce starts a campaign against him, giving a televised speech for people not to lose hope and to vote against the Joker.
The Joker strikes next at a charity circus where Bruce and Silver are in attendance. There, in disguises are the Penguin as the ringmaster, the Riddler as a clown, and Catwoman "sexily decked out as a trapeze artist". Catwoman pours acid on the trapeze of the Flying Graysons ("the main attractions"), John and Mary fall to their deaths, while young Dick miraculously survives by falling into the bales of hay on the circus ground - “The effect is like a baby bird falling out of a tree into a nest.” Running to the sobbing Grayson's side, Bruce scoops him up and carries him to his car, promising him that "As long as I live, you will never be alone." Burton describes Dick as “a charmer: a clever little wise-ass with a loving heart. He’s pale-skinned to the point of ghostly, defined by an alert little face and carrot-colored hair (sort of a new-wave Artful Dodger).”
Burton uses the parade sequence with balloons filled with his deadly laughing gas that would appear in the 1989 movie. There is a confrontation between Batman and The Joker that results in both being carried off by the balloons. When they both crash through the skylight of the Gotham Museum, it's up to the new hero, Robin, “a flash of red and green” with a “devilish mask”, to save Batman's life. When Batman throttles the Joker and puts a gun to his head, Commissioner Gordon arrives, puts a hand on Batman’s shoulder and stops him from making a choice that would ruin his life (much better than the giant thumbtack scene). The treatment ends on Christmas morning as Bruce, Dick, Silver and Alfred open up presents... the last one is wrapped in purple and green and has a clownish face on it.
Where as Uslan and Melniker wanted a living comic book action film, Tim Burton delivered something far more interesting and artistic and three-dimensional. By blending 1930s Warner Brothers gangster films with 1920s silent horror movies, he really brought Batman's world to life in a way no one thought possible.
The sequel went through almost as many scripts as the first film, despite it taking only three years to make. The original idea for Batman II: The Next Adventure was proposed by Sam Hamm and reportedly featured the transformation of Harvey Dent into Two Face after failing to convict the Joker, who survived the fall at the end of Batman. Warner Brothers felt Two Face was not a popular enough character to be the lead villain and rejected Hamm's proposal, demanding the more well known Penguin and/or Catwoman be used.
So, Hamm shelved Batman II (apparently, the plot was recycled by William Loebs for the Batman syndicated comic strip that was circulating after the first movie) and began work on a new script titled Batman Returns, and once again it was excellent. Set at Christmas time, the plot deals with an obese, aristocratic criminal named Mr. Boniface (alias the Penguin), who has spent the last thirteen years in jail for stealing 40 million dollars. He makes a deal to return the money for an early parole. Of course, he had it in the bank, and made millions of dollars in interest during his jail term. Penguin hires the erotic Eurasian cat burglar Selina Kyle to steal five raven statues from the founding five families of Gotham, and frame Batman for the murders.
Echoing the "Purrfect Crime" episode of the 1960s TV show, the ravens are a map that lead to a treasure. Unknown to Bruce, the map leads to where the treasure is buried--in the Batcave. Harvey Dent is no where to be found, but Gordon, Vicki, and Alfred are all back, as well as a group of wanna be teen vigilantes who hero worship Batman. At one point, Vicki is rescued by an orphaned homeless kid named Dick Grayson who seems to be quite an acrobat. Later, the kid helps Batman escape from the cops, and ultimately moves into Wayne Manor just before Penguin and Catwoman invade the place. Unfortunately, Tim Burton felt the script read too much like a sequel. Granted, the finale also seemed quite rushed and there never was any resolution with the storyline of the teen vigilantes. A second draft would be needed to correct these problems.
There are unconfirmed rumors the original plan was to have a now corrupted Harvey Dent, whose goal was to groom mob boss Penguin into a mayor Dent could control. Selina Kyle went from being an amorous cat burglar to Dent's mousy secretary. For the planned climax, as Batman, Catwoman, Penguin and Dent collide at Pengy's zoo hideout, Dent's fate was to be sealed as an exploding air conditioner burns and scars the left side of his face. A snag in planning the script happened when Warner Brothers, who were allegedly not happy with Billy Dee Williams' performance as Harvey Dent in the first film, bought him out of his contract for the sequels. Allegedly, Warners never wanted Williams cast as Dent in the first place. It's rumored the studio's top picks were Dale Midkiff (Pet Cemetery) and Don Johnson (Harvey Dent in Batman The Animated Series looks strikingly like Don Johnson), but Burton cast Williams. So Waters reworked Dent's planned role in the script for retail mogul Max Shreck, with Christopher Walken ultimately landing the role. While Max did not appear in Hamm's draft, Shreck's Department Store did.
Danny DeVito had been cast as Penguin, suggested to Burton that Oswald Cobblepot be a disgusting sewer dwelling mutant. Burton loved the concept, and Waters worked in DeVito's vision of the Penguin. Waters, under Burton's suggestions, also made a drastic change to Dick Grayson. Now an African American character known only as "The Kid", he was a teenage mechanic who helps Batman repair the Batmobile and escape from the cops, and later is recruited to help stop the army of penguins. Burton liked Waters' draft much more, but rewrites were needed.
It is a shame Burton and Keaton never had the chance to conclude their Bat-trilogy. Perhaps there may still be an opportunity, as I think reuniting Burton, Keaton, Nicholson, Pfeiffer, and Sam Hamm to make a film adaptation of Frank Miller's Dark Knight Returns graphic novel would be a Batman fan's dream come true.
