That Loki is impressive as hell. "The Graham Norton Show" alongside Robert De Niro, Anne Hathaway, and Kenneth Branagh -- what a great lineup! -- and the conversation turned to impressions.

Tom Hiddleston stole the show, and started his mimic-fest by doing an impression of Owen Wilson from "Midnight in Paris." Tom said he's been made to do impressions of his "Avengers" co-stars, and admitted a Christopher Walken impression is easy ... but pretty much irresistible, so he did that too. Then he braved a De Niro impression, on the same couch as De Niro.

Tom said he's memorized pages of the "Heat" script and re-enacted a scene, acknowledging that De Niro would be familiar with it, since he was there, shooting the 1995 scene with Al Pacino. It's kind of hilarious to see Tom explain the scene as if he is the expert, but he's self-deprecating about it and it's very charming, especially when he demonstrates both roles for De Niro.

Watch and love:


Ten points to Gryffindor for the bravery to attempt that scene in front of the legend. De Niro seemed to appreciate it. At least he was a good sport about it. You have to imagine he gets "you talkin' to me?" a thousand times a day, so he must have patience about these things.
