In 1969 Barbara Hershey met David Carradine while they were working on Heaven With a Gun. The pair began a domestic relationship that would last until 1975. Carradine said that during the r*pe scene in that movie he cracked one of Barbara's ribs. They appeared in other films together including Martin Scorsese's Boxcar Bertha. In 1972, the couple posed together in a nude Playboy spread, recreating some sex scenes from Boxcar Bertha''. Later in 1972, Hershey gave birth to their son, Free, who changed his name to Tom when he was 9 years old. The relationship fell apart, around the time of Carradine's 1974 burglary arrest, after he had begun an affair with Season Hubley who had guest starred in Kung Fu.
