Paramount Pictures has postponed the release date of Sky Captain and the World of Tomorrow from June 25 to September 17 in an effort to protect the retro-futuristic version of a Saturday morning serial from Spider-Man 2's potent box office clout.  Originally scheduled to debut on July 2, the theatrical release of Spider-Man 2 was recently moved up to June 30 (see 'Spider-Man 2 Moves to Wednesday'), which provided Sky Captain with a very short window of opportunity before facing the wallcrawler's potential mega-blockbuster.  But arachnophobia is only part of the answer to the change of release dates, Sky Captain, which stars Jude Law, Gwyneth Paltrow, and Angelina Jolie, was entirely shot in front of a bluescreen and only half of the special effects shots have been finished at this time.  The September release date takes the pressure off the numerous special effects houses working on the Sky Captain project.  The later release will also allow Paramount to preview and promote the film heavily at the San Diego ComiCon International in July.
