20 Things You Didn't Know About Batman & Robin
12. An Entire Poison Ivy Sub-plot Was Abandoned
Character development was never exactly Batman & Robin's strongpoint, but an entire subplot revolving around Uma Thurman's Poison Ivy was shot, only to get left on the cutting room floor during post production.
Bruce Wayne and Pamela Isley were originally set to do a bit of extended flirting that would see the billionaire playboy ditched by his squeeze, leading him to wonder why he was so fixated on the mystery woman. Bruce and Alfred would then hit the books and do some research before eventually discovering that Isley and Poison Ivy were one and the same.
Instead, the production decided to ditch the eleaborate backstory altogether and simply have the dots connected by a couple of photographs and a lightbulb going off in Bruce's head.
