This is where I'll put any short films starring The Simpsons, aside from the Maggie Simpson in... shorts.
The Good, the Bart, and the Loki (6:29)
Disney+; IMDb; TV Tropes; Wikia; Wikipedia
This was released on Disney+ on July 7, 2021. It's actually only about 4 and a half minutes, before the foreign credits fill out its runtime. So... Loki gets banished from Asgard to Springfield, where he begins living with the Simpsons. Bart gets him to zap Lisa to Asgard, where she picks up Thor's hammer and gains his power, then returns to Springfield to fight Loki. But of course there's a twist ending. There's also a mid-credits scene and two post-credits scenes, the second of which parodies the Disney+ series Loki. It's all pretty cool, if incredibly rushed.
