After taking a back seat in "Thor:The Dark World" Loki will return in full villain mode in the third Thor movie. But will that be the swan song of the new English superstar?

Marvel found Hiddleston's popularity a huge surprise but they already had him cast as the main villain for The Avengers. Even with that kind of exposure, the demand for more Loki just strengthened.

It is doubtful that he'll be in "Avengers: Age of Ultron" but he will play the major villain in "Thor 3." The likely story they have is Ragnarok-the end of all things. Hiddleston discusses that with Movieweb:

"I think that in the comic book, the sort of end of days, Armageddon aspect is probably the direction in which it will all head in. Where it's sort of the end of all things. There's obviously no script or anything. When I read the comic books, I thought it was an interesting way to go."

"I think there are very interesting things that happen. In the mythology, when you get into Ragnarok, which is the "end of all things", it's not the end of the world...It's the end of time, and the universe, and space.

And I think, if I am correct...Loki essentially, sets that in motion. And his motivation for doing so is intriguing and he almost becomes the incarnation of chaos, in a way...So I think that can be quite new.

Loki is a character who's existed in popular consciousness for 3,000 years, so there are many, many iterations I could explore...It's just a question of whether audiences would want to see him again."

"Well, I guess it's all quite open-ended. I don't know when or how...And you know, I do worry about sort of...Overstaying my welcome, in a way. I mean, I've had such a great run, but...I guess we will just have to wait and see."

Ragnarok in Norse mythology was subjected to a slightly different interpretation in the comics. It is also expected that the cinematic version will be altered.

The more glaring implication is that such a storyline has a tone of finality. It will probably bring about the end of the Thor trilogy and possibly the last appearance of Tom Hiddleston as Loki.

But in the comics world, death is not usually final, especially when you're dealing with 'gods' and immortals.

Would you like to see Tom Hiddleston beyond 'Thor 3?'
