I like all of the above (Wrestler, Rourke, Tomei, Slumdog).
The Wrestler was among Rourke's best acting work to date, and it's a shame he didn't get the Oscar. But then, the same is true of Clint with Gran Torino, which was completely ignored by Oscar this year. I'd put Gran Torino up there with Unforgiven as Clint's very best.
