Tom Hiddleston is a classically trained actor, but do you think that he'll be typecast as Loki because the Avengers movie is so popular and he was relatively unknown before it came out?
I hope not, but it's just credit to the fact he plays Loki so well. I think he can escape being only seen as an angsty villain, I can easily imagine him in a completely different role. Chris Hemsworth was pretty unknown too... but he doesn't have as many fangirls as Loki I don't think haha.
My name is Jade too :-)
I don't see how he will be typecasted because I haven't seen much of him outside of the Marvel movies. But I doubt he will play again the "evil genius masterminded coveted by all the fangirls despite he being the main villain" character in his other movies.
