I once got my collar felt for flying closer than 60m to a cameraman on a film job as part of a stunt. The exemption in place allowed us to fly up to 60m. When I politely pointed out that I had landed next to the cameraman (circa 20m) the Ops Inspector soon went quiet once the penny dropped...
As a film pilot you need to know the regs, the rules (especially Rule 5&6 in the UK) along with the exemptions you have at your disposal.
