Filming The Trap (1966) with Oliver Reed was quite the experience. Oliver was such a ruff and aggressive character. In the fight scenes we had to ask him to be more gentle with the other actors.
That's right...The film industry is the exact same thing, it just gets more sophisticated the higher you go.
Whenever I've had a difficult movie and questioned whether or not the business is worth it, ...I say to myself: 'well, I'm sure the next picture is going to be a lot easier'.
