The Simpsons: O C'mon All Ye Faithful

The Simpsons: O C'mon All Ye Faithful (2024) is a holiday short from Springfield's first family that you can watch online on iFILM. Forty-five minutes, one mission: round up some Christmas cheer.

The town turns its hunt for holiday spirit into the usual Matt Groening chaos. The regular voice cast is all here — Dan Castellaneta, Julie Kavner, Nancy Cartwright, Yeardley Smith, Hank Azaria and Harry Shearer. Guest faces drop by too: mentalist Derren Brown, singer Patti LaBelle and the a cappella group Pentatonix, who hand the episode its musical hook. Quick, tuneful and a little cheeky, it plays as easy seasonal viewing with no season-long plot to track. Stream The Simpsons: O C'mon All Ye Faithful (2024) online on iFILM.
