Casting

Although Robbins pushed for 29-year-old Carol Lawrence, the first Maria, to be cast in the same role in the film, after seeing her screen test the producers agreed she was too old to play the part. A number of other cast members from the Broadway and West End productions were cast in the film. Tony Mordente, who played A-Rab on stage, was cast as Action in the film, and George Chakiris, Riff in the London stage production, played Bernardo in the film. Tucker Smith, who joined the Broadway production several months into its run, played Diesel, renamed Ice for the film. David Winters, the first Baby John on stage, played A-Rab. Eliot Feld, an ensemble member and understudy for Baby John on Broadway, played Baby John. Jay Norman, Juano on stage, appeared as Pepe. Reprising their stage roles in the film were Carole D'Andrea as Velma, Tommy Abbott as Gee-Tar, and William Bramley as Officer Krupke.
