My Toy Story is an upcoming film by The S Way and Fun Studios with credit from Disney/Pixar (they are only involved in creating the actual Toy Story.) It is meant to have the reverse events of the entire film. For example:
Toy Story: Woody attempts to get Buzz behind the desk, but circumstances lead Buzz ....... out the window! Also, Woody is all like: "BUZZ!" which means he's nice.
My Toy Story: Buzz gets Woody to be knocked out the window on purpose (not a nod to Woody's original mood), but ends up under the desk, and Buzz is all like, "YES! WOODY'S GONE! WOO HOO!" which means he's not as nice as Woody. However, Woody was supposed to knocked out of the window on purpose, but ended up getting "opposite-ized".
It is currently scheduled for a 2011 release.
4 sequels have been announced, which are My Toy Story 2 (opposite Toy Story 2) and My Toy Story 3 (opposite Toy Story 3), and, similar to the Diary of a WImpy Kid series, My Toy Story 4 and My Toy Story 5 are "non-opposite-ized" continuing adventures at Andy's (Andy and Bonnie's roles are switched, was originally not supposed to happen when it was announced on June 28, 2010). This is the only upcoming film to have sequels (the text treatment for the first flim is still being written).
