Fifteen million euros for machinima? Where is the money going?
I can see how Source would be a good way to make a reasonable-looking animated movie on the cheap. But with a reasonable amount of money to spend, then either:
a) You're reusing enough existing stuff (character models, physics enginey stuff, et cetera) that you can't possibly spend that much money, or
b) You're re-doing enough stuff from scratch that there doesn't seem to be much advantage to doing it in Source rather than something more conventional like Maya [or whatever they're using nowadays]
