Maybe the producer also insisted HE do what he was booked to do!
Why doesn't he just walk off the set you say? Probably for exactly the same reason that the girl didn't just walk off the set, 'using dollars instead of a weapon' including maybe the threat of losing work in the future.
One last thing, what the fucking fuck does 'an underage girl (but legal in that area)' mean? This is just self contradictory nonsense: is the girl underage or isn't she, she can't be both!!!
