Comic-Con International announced Thursday, July 21 movie panel schedule for the 2011 edition of the pop culture megatest and as expected "The Twilight Saga: Breaking Dawn, Pt. 2" is the major highlight of the day.  Moreover, it appears 20th Century Fox was the only major studio willing to brave the publicity onslaught the return of Kristen Stewart, Taylor Lautner and Robert Pattinson will bring on the Con's first full day of operation. Of course, they have a good three-hour break to let attendees hearing return to normal after what is sure to be a screamfest of euphoria for the arrival of "Breaking Dawn's" cast and crew.  The convention organizers did surprise, however, with the participation of Cannes winner and critic's winner "Drive" starring Ryan Gosling, Carey Mulligan, Ron Pearlman and Christina Hendricks (although we're hoping Albert Brooks is a surprise guest).

The schedule for Friday the 22nd, Saturday the 23rd and Sunday the 24th is expected to be announced over the next three days.  Comic-Con also revealed this year's TV panels for Thursday which include fan favorite "Game of Thrones." A complete rundown of the movie-centric panels are as follows.
