Eli Wallach as Mr. Freeze
Known for his role as Tuco in The Good, the Bad and the Ugly, Sergio Leone’s iconic spaghetti western, and his debut performance in Baby Doll, directed by Elia Kazan and written by Tennessee Williams, Eli Wallach appeared on Batman only because his children pushed him to go for the part. Mr. Freeze was played by two other actors during the show’s run — George Sanders and Otto Preminger, both stars who appeared in Hitchcock films.
