Free movies sites for IPhone please?

Don't reccomed netflux cause it's rubbish

Netflix is only free the first month. Try the TV network websites a few of them have apps. I think you are thinking of Crackle which is free but has less good stuff then netflix.
Since you say rubbish do you live where the BBC app work for video where you live?

Crackle
Hulu
Crunchyroll (for anime)
Viewster

Amazon Prime (Free 30 day trial)

Netflix is by far the best. You can rent movies in itunes also.
