The new James Cameron animated effort "Avatar" is supposed to be one of the biggest movies of the holiday season. It's certainly getting big promotions.

The new trailer for the film, set to open in theaters on Dec. 18, will be shown on the world's largest video display - Cowboy Stadium's Diamond Vision Screen - just before the kickoff of Sunday's game.

Fans who tune in to "Fox NFL Sunday" just before 10 a.m. Sunday on KMPH (Channel 26.1) will be able to see the three minutes and thirty seconds trailer. This will make it the largest live motion picture trailer viewing in history.
