Mel Gibson is reportedly furious that producers of The Hangover 2 replaced him with Liam Neeson after Hangover cast members objected to working with him. (Gibson had a minor role as a Thailand tattoo artist.) Alan Nierob, who represents Gibson and Neeson, even quipped, in a statement: “Neeson will take the role, pending clearance of cast and crew.†A source said Gibson, charged with assaulting his ex-girlfriend and being insane, “doesn’t understand why Mike Tyson, a drug user who turned his life around, was given a chance while [he] was kicked to the curb,†but if Mike Tyson is your best analogy, you might not be cast in quirky comedies so quickly.
