TV Episodes That Could Make An Over Hour Long Movie

There have been nearly 1000 episodes but there are some that could make a good movie. Would like to know which episodes you think could be edited and made a movie out of. I think one good lot would be the Kyogre and Groudon ones at the start of season 8. They did this with 3 chronicles episodes to make one for DVD called The Legend Of Thunder.

I would say any of the episodes with the league battles could be put together and presented as movies,, along with putting the episodes that feature the evil groups/organizations of the series.
