‘Shrinking’ Season 3 Trailer Reveals First Footage of Michael J. Fox’s Acting Return

Michael J. Fox has made his Shrinking debut.

On Tuesday, Apple TV released the trailer for the third season of Shrinking, which stars Jason Segel and Harrison Ford. In the trailer, Fox meets Dr. Paul Rhoades (Ford) in a waiting room.

“What are you in for?” Fox asks Paul. “Parkinson’s. You?” Paul responds, to which Fox jokes, “Just a haircut,” and they both start laughing.

Paul’s had Parkinson’s since season one. However, he initially tried to hide it until he realized he needed to face his disease.

The guest role marks Fox’s return to acting after stepping away in 2020 due to memory and speech issues from Parkinson’s disease.

Shrinking follows Jimmy’s (Segel) grieving therapist, who began breaking the rules by telling his clients exactly what he was thinking — and ignoring his ethics. By doing so, he found himself making changes in people’s lives as well as his own.

Fox joining the show marks a reunion for him and series co-creator Bill Lawrence. The two previously worked together on the ABC sitcom Spin City for four seasons, which Fox starred in until 2000, when he departed due to Parkinson’s-related issues. Fox also had a guest role on Lawrence’s Scrubs.

In addition, the trailer shows Cobie Smulders reuniting with Segel after a brief role in season two, and she plays his love interest, Sofi. They previously co-starred on the hit CBS sitcom How I Met Your Mother.

Shrinking season three will premiere its first episode on Wednesday, Jan. 28, followed by a weekly episode release until April 8, 2026, on Apple TV.
