Several actors from the first film did not return for the sequel. Marlon Brando initially agreed to return for the birthday flashback sequence, but the actor, feeling mistreated by the board at Paramount, failed to show up for the single day's shooting. Coppola then rewrote the scene that same day. Richard S. Castellano, who portrayed Peter Clemenza in the first film, also declined to return, as he and the producers could not reach an agreement on his demands that he be allowed to write the character's dialogue in the film, though this claim was disputed by Castellanos widow in a 1991 letter to "People" magazine. The part in the plot originally intended for the latter-day Clemenza was then filled by the character of Frank Pentangeli, played by Michael V. Gazzo.
