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 Zoolander star previously directed most of the first two seasons of Severance, working on 11 of the show's 19 previously aired episodes. He will still serve as a writer and executive producer for season three, but will leave the director's chair for someone else.
