Tom Hiddleston, who plays Loki in Thor and The Avengers, also does impressions. Someone put together a compilation of some of these impersonations, most of which were impressions of people he’s worked with, including his Avengers co-stars Chris Evans and Samuel L. Jackson.
In the first video below, he does impersonations of Alan Rickman, Owen Wilson, the abnormally-large velociraptors in Jurassic Park, Chris Evans, Orson Welles, Samuel L. Jackson, then finally ends with a Sarah Jessica Parker impression. *punches another hole in the SJP Horse Jokes Club Card* Oooo, just two more punches away from a free bag of oats.
The second video below gives the context for that Jurassic Park raptor impersonation (as if we need context).
