In terms of movie-related programming, the San Diego Comic-Con ends on Saturday. The schedule for Sunday, July 25th is now online and it’s "Kids' Day". That means there are a lot of Nickelodeon and Disney Channel panels as well as craft panels and screenings that are perfect for parents.

For geeks though, Sunday is all about picking up that last-minute collectible, walking the floor, or seeing some TV panels. Hall H isn’t even open on Sunday, so instead all eyes turn to the second biggest room, Ballroom 20, where the biggest panel of the day by far is the one for Glee. But that’s not all.  Smallville, Supernatural and Castle all will have presentations on Sunday too. And panels featuring Sons of Anarchy and It's Always Sunny in Philadelphia are pretty much guaranteed to slap Kids' Day in the face.

You can check out the schedules for Thursday, Friday, and Saturday at their corresponding link. Hit the jump for our highlights of the 2010 San Diego Comic-Con's closing day.
