Karen Gillan has joined the cast of Apple TV’s Shrinking for Season 4 in a recurring role, marking a major addition to the acclaimed dramedy ahead of what will be a significant shift in the show’s direction.
Gillan, known for her Marvel roles as Nebula in the Guardians of the Galaxy films and her early breakout in Doctor Who, will appear alongside returning series stars Jason Segel, Harrison Ford, Christa Miller, Jessica Williams, Luke Tennie, Michael Urie, Lukita Maxwell, and Ted McGinley. The exact details of her character are being kept under wraps.
Season 4 marks a fresh creative chapter for the show. The season will feature a time jump and an entirely new storyline, departing from the narrative threads of the first three seasons while keeping the core ensemble intact. The show’s creator Bill Lawrence announced this shift in creative direction earlier this year, noting the season would reset while maintaining the cast that audiences have grown to love.

Shrinking, created by Lawrence, Segel, and Brett Goldstein, was renewed for Season 4 ahead of the Season 3 premiere. The dramedy has become a critical and audience favorite, earning nine Emmy Award nominations across its three seasons to date, with acting nods for both Segel and Williams and a nomination for outstanding comedy series in 2025.
