TV and film extra work

[W124Bob]

As I take early retirement by the end of the tax year I'm interested in looking at TV/film extra work for bit bit of hobby money. Early starts and long days are no problem(do those now), live in south Manchester so plenty of choice just curious as to what to expect. Are fees taken as a one off or per job, HMRC, do I do my own photos etc?

Thanks for the replies, re Paranoid the police station exterior is a Quaker meeting house in Sale with the interior used for a small scene(AA type meeting). I certainly won't get stage struck and I was aware of the pecking order rest of the info is useful.
