Entertainment Tonight.Keaton, who played school teacher Kay Adams-Corleone in the film opposite Pacino, said it was “weird” she was cast before the actor, given that the film is based wholly around his Mafioso character.“I had been cast before Al Pacino in Godfather 1! Is this not weird?” the Oscar-winning actress said. “What would ‘The Godfather’ have been without Al Pacino? It’s just one of those weird, unusual things in life.”Keaton was present during Pacino’s second audition execs ultimately “gave him the job.”“Do you believe that? After he had auditioned before and they didn’t want him,” she said.The hit film, which later became a trilogy, was based on Mario Puzo’s 1969 novel of the same name.And despite the fact the novel topped all bestselling lists, Keaton admitted she didn’t read it before auditioning for the film.“I think the kindest thing that someone’s ever done for me … is that I got cast to be in ‘The Godfather’ and I didn’t even read it.
