According to the British documentary The Godfather and the Mob (2006) (TV), Caan was regularly seen with Gambino family underboss Carmine Persico (aka "Junior") during the filming of The Godfather (1972). As Persico was under surveillance by the FBI at the time, Caan came under almost equal scrutiny.
After being turned down by Jack Nicholson and Al Pacino, Julia Phillips inquired of Caan's agent if he would be interested in taking the lead role of Roy Neary in Close Encounters of the Third Kind (1977). Caan's agent responded that he would read the script for a guarantee of $1 million plus 10% of the gross if he accepted the role. Phillips went with the original choice, Richard Dreyfuss.
