Character actor John P. Ryan was born on July 30, 1936 in New York City. The son of Irish immigrant parents, Ryan graduated from Rice High School and studied English at the City College of New York, where he first developed an interest in acting.

Other notable movie parts include the fanatical Colonel Hardcore in Shamus, shrewd mob capo Patsy ONeill in the witty Cops and Robbers, evil scientist Schneider in Futureworld, the dogged Lt.
