Stiller has directed most episodes of the Apple TV hit so far, but season three poses some scheduling conflicts.

With a hit TV series, a documentary about his parents, a WWII movie and 'Focker-in-Law' in the pipeline, Stiller, near 60, isn't slowing down: 'You only have so much time.'

The streaming wars have been going on for years now, with every service offering a handful of mega hit originals. Those with an Apple TV+ subscription know that Severance is at the top of that list, with fans eagerly anticipating the third set of episodes.
