Now that residents of Mexico are sticking as close to home as possible, movie studios are having to readjust their international calendars.

Earlier this week, 20th Century Fox chose to indefinitely postpone the premiere of Wolverine. Now Paramount is following suit with the debut of Star Trek. That sci-fi prequel had been scheduled to open on May 8.

Unless the swine flu situation plateaus soon, other blockbusters could be added to the casualty list. Sony is currently monitoring events for the May 15 release of Angels & Demons. Meanwhile, Night at the Museum: Battle of the Smithsonian - another Fox release - could also be pushed from its May 22 slot.
