The Simpsons, The O: The Movie, The Amazing Spider-Man, and The Dark Knight Rises are back on the airwaves in a special three-hour special airing Saturday, Oct. 20 at 8/7c.

The Simpsons will air for the first time in two decades, but The O and The Amazing Spidey are not returning, but the two will continue to appear onscreen as guests.

Also returning is The Dark Knights Return: Part 1, an upcoming live-action adaptation of the comic book series, which follows Batman and his new allies in a live-fire battle against a terrifying new threat to Gotham.

(The new series premieres October 13.)

And The O will return for a third season, this time as a three-part special.
