In a recent podcast appearance on Toon’d In with Jim Cummings, actor Alan Tudyk opened up about a lesser-known chapter in his career involving the 2004 sci-fi thriller I, Robot.

Known for his versatile voice work and motion capture roles, Tudyk shared how his performance as the robot Sonny apparently stole the spotlight in test screenings—so much so that it resulted in him being sidelined from the film’s promotional efforts seemingly for overshadowing the film’s star Will Smith. This revelation adds an intriguing layer to the film’s history, hinting at the delicate egos and studio politics that often shape Hollywood blockbusters.
