Premium content - I like that idea. I would donate $50 towards a 'marathon', (defined as at least 3 x 2 hour movies or 2 x 3 hour movies, etc). Star Trek, Potter, Bond, Pirates, etc.
Also, there are still a few gaps in the big tentpole genre series to fill in (e.g. Transformers 3). And coming up in 2012 are some big ones to knock over: Prometheus, Avengers, TDKR, etc.
Or old genre classics (e.g. Total Recall 1990 - perhaps doubled with the 2012 version). Or overlooked left-field movies e.g. Mr Nobody. Or TV episodes. Or shit movies for fun sneering e.g. AvP. Personally I'd like some historical epics be given the DiF treatment.
So there should be lots of Venn Diagram overlaps between DiF and the forum, so that no one feels pressured commentating on or paying for stuff they're not interested in.
Just to put my cards on the table and some figures...
For individual movies, I would say $10 is a reasonable price. I'd pay $10 towards commentaries for King Kong 2005, Benjamin Button, Troy (Extended), Kingdom of Heaven (Extended), Gladiator, Alexander.
I'd pay $50 towards a 3 x King Kong treatment, Millennium Trilogy (extended), Pirates 2,3,4 and maybe even the Underworld series. There's probably many more options - I'd have to think about it if some business model became more concrete.
Does anyone else like the concept of original & remake as a double-feature?
