Arthur/Eames is the biggest slash pairing to come out of Inception,the Joseph Gordon Levitt character (Arthur) and the Tom Hardy character (Eames). Insanely hot is what you get from both characters in the movies. I haven't read much fic but there is a community, inception fic, is the name I think,they probably have some good meta. There is definite slash quality between them in a snarky kind of way, Personally, I was more intrigued with Ariadne (Ellen Page).
