My taste in movies tends to be a little out of the mainstream, so, that said:
You probably have seen these, but here goes:

Adaptation, with Nicolas Cage (usually can't stand him, but this is a strange, interesting movie and he's good in it)
Gangs of New York, with Daniel Day-Lewis
There Will be Blood, with Daniel Day-Lewis
Snowpiercer, with unforgettable performance by Tilda Swinton

Well, good luck. At least you have great company :)
