Apple Computer, which has long maintained that the best way to combat Internet piracy is to offer music and video at reasonable prices, found itself the victim of pirates Tuesday. The trailer for Sam Raimi's Spider-Man 3, starring Tobey Maguire, Kirsten Dunst and Topher Grace, was supposed to premiere at Apple's iTunes Music Store Tuesday night, at about the same time it was to debut in theaters in advance of late-night screenings of Superman Returns. However, it appeared earlier in the day on the YouTube.com website. One blogger speculated, "It looks like a projectionist or an inside source at a movie theater was able to videotape the trailer and upload it to the Internet." The film is currently scheduled to open May 4, 2007.
