With the rebels movies, both of them combined turn about 6 hours of the show to about 3 hours 30 mins of movies.
Here’s the link to the first movies IFDB page, made by HarryBowls: https://ifdb.fanedit.org/star-wars-rebels-episode-i-spark-of-rebellion/.
The movies basically focus on the core story and try to cut out as much ‘filler’ as possible.
PM me for further questions so that we don’t flood the Clone Wars forum with Rebels stuff.
If they cut out all the filler, they could’ve fit season 1 into a single movie. Okay well you’d have to cut the Tseebo arc, but is it really essential?
