Arnold Schwarzenegger revealed his reaction to son Patrick Schwarzenegger getting naked on camera as they paired up for this year’s edition of Variety’s “Actors on Actors” series.

The action hero and the rising star discussed everything from nudity to nepotism in the hour-long conversation, which was released on Tuesday.

During the chat, the championship bodybuilder and ex-governor of California explained how it took him time to stop getting typecast as a muscle man, telling his son, “‘Terminator’ was the first time that I was doing a film that had nothing to do with the muscles. It was with leather jackets on and being a machine.”

But he did admit that his brawny build came in handy during his first scene in the action classic, where his cyborg assassin character time-travels back to 1984 Los Angeles wearing absolutely nothing.

“Only the opening scene was naked,” Arnold recalled. “But I’m talking about naked.”
