He transitioned into live television in 1948, appearing in anthology dramas and then moving to Hollywood, where he gained supporting roles in feature films. Harris’ work spans both episodic television and film, with recurring collaborations with directors and producers in drama, action, and science-fiction genres. He became widely recognized for his television work, particularly as Dr. Zachary Smith on Lost in Space, where his performances combined character-driven comedy and villainy.
