The Salkinds and Spengler knew that Brando was their biggest selling point not only because of “Superman” itself, but also because of the legality of the production in general. Brando’s casting enticed Gene Hackman to sign for the role of Lex Luthor, and the film only evolved from there.
Still needing to work out who would actually direct the film, the producers figured out who was behind the hit movies at the time, landing on the veteran TV director (still is a fledgling filmmaker) Richard Donner, who just delivered a terrifying smash on “The Omen.” Like Donner remember back in 2016, Alexander Salkind called him and said, “I don’t have a director and I’ll pay you a million dollars.” Undoubtedly, one of Salkind’s hit spots was his stars, with Donner recalling how the producer told him “I have Marlon Brando for X number of weeks and I have Gene Hackman, and we started head turned on such a day.”
Donner was immediately sold out when he got the chance, and was even more motivated when he saw the state of the script, explaining that it disparaged Superman so badly that he “wanted to do it just to protect himself.” protect him.” While “Superman” and its production woes are far from over, at least the movie can finally be made without any further international deportation issues.
