Jason Segel has played a lot of funny characters in turmoil, whether that’s as a young person in the throes of angst in “Freaks and Geeks” or as someone recently dumped while on a Hawaiian vacation in “Forgetting Sarah Marshall.” He keeps that trend going in the Apple TV+ series “Shrinking,” where he plays a therapist who’s dealing with his own tragedy. Jason tells Tom about the “magical melancholy” in his roles and why he left L.A. after the massive success of "How I Met Your Mother."
