The now-renowned directors Quentin Tarantino and Roger Avary got their first Hollywood job in 1986 as production assistants on Dolph Lundgren's workout video : Maximum Potential. The director John Langley knew them from the videostore where Tarantino was working.
John Langley said: "I wrote a screenplay that sold years later. Then in 1987, I made the Dolph Lundgren: Maximum Potential exercise video. I hired Quentin Tarantino and Roger Avary as PAs. Quentin and Roger worked at Video Archives in Manhattan Beach, where I live. They were kids, 18-19 years old. We used to discuss film and BS. I loaned him my script for the  film Behind Enemy Lines. He showed me scripts he'd written.
"As a PA, Quentin was always bashing into nightstands and babbling everybody. He's quite a talker and loves to get into debates about film. My partner would say, 'Fire that kid. He doesn't know what the hell he's doing.'
"Roger came to me once and asked, 'I want to be a director. I don't want to be a PA. How do I do that?' I said, 'Roger, if you want to be a director, direct. If you want to be a writer, write. If you want to be a producer, produce.' He thought about it and said ok. The next day he came in and said, 'I quit.' I said, 'That's cool. What are you going to do?' He said, 'I'm going to be a writer and a director.'" from John Langley's profile
"In 1985, things move at last. One of the clients, John Langley, hires him [Tarantino] as an assistant on a Dolph Lundgren film : "It was a gym thing, we shot on the Venice Beach lawn. The problem is, it was covered of dog shits", remebers Langley."I had my day taking off dogs mess. Years later, I got myself in an elevator with Lundgren. I was saying to myself : there is the guy I cleaned a lawn for...", tells Tarantino" from Le Nouvel Observateur, October 1996 (translated from French)
"It's now part of Hollywood mythology that Quentin Tarantino's first real job on a movie set saw him cleaning doggie doo-doo off lawn on which Dolph Lundgren was going to perform for his workout video." from Impact (UK), May 1997
