The actor had already done several auditions with Cates and felt comfortable with her, saying, “When it came to the session for Gremlins, I rested my head on her shoulder and gazed at the camera. I’m told Steven Spielberg said: ‘Oh my God, look at that! He’s in love with her already. I don’t need to see anything else.’”
