thanks all. i havent had the contract through yet, its all been agreed by email so far.
yes there is a set amount for deferment, and yes i suppose i just have to hope they are honest - i have personal assurance from 3rd party that they are good people and they do seem really nice and we hope to work together again sometime, so hopefully it will all work out - i only agreed to it because its quite a lot of money for one extra day - more than the 2 other days put together - and it was either agree to it or only take the lesser immediate 2 day payment and just dont turn up for the last day ...
so, figured i may as well accept that as its only one extra day... and i wasnt doing anthing else that day, and i didnt want to just do half a job and let them down - its my name on it after all.
if i dont get anything i wont have lost anything really, if you get me, just a day of my time.
is there a way to check what a film earns?
