Early life[ edit ] Haim was born in Toronto , Ontario , the son of Judy, an Israeli-born data processor, and Bernie Haim, who worked in sales. He made his feature film debut in 's thriller Firstborn , as a boy whose family comes under threat from his mother's violent boyfriend, played by Peter Weller. Weller collared Haim, throwing him up against a wall to warn him not to speak to him after a take. It took three assistants to separate them. Weller apologized to Haim for the incident and attributed it to method acting , as he was trying to stay in character for the villainous role he was playing. I was 10, and I'll never forget we went to like a crew party and my mom and dad were like dancing with other people and it was rocky; and I just started crying, whatever, and I remember Sarah pulling me outside with Robert Downey, Jr.
