Liam Neeson, who took over the role originally offered to Mel Gibson in The Hangover Part II, will not be appearing in the movie after all. Even though Neeson had completed filming all his scenes, the director, Todd Phillips, decided he needed some reshoots. Unfortunately, Neeson is already at work on Clash of the Titans 2 and is not available, so Phillips has recast the role. The director initially offered the role to Gibson months ago, but backed down after cast members objected. The scenes are now being reshot with actor Nick Cassavetes. The Hangover Part II trailer was already shown in some theaters in the States, but was yanked after it was discovered the spot hadn’t been cleared with the Motion Picture Association of America (MPAA). In the trailer, a monkey imitated a lewd act. The Hollywood Reporter reported that the trailer, which is rated R, debuted April 1 as a preview for Source Code, which is rated PG-13 in the States. A revised trailer will be seen in theaters this Friday.
