MSN UK: Tom Hiddleston has revealed that he isn't sure if he would return for the Avengers Assemble sequel.
The British star, who portrayed Thor villain Loki in Joss Whedon's first film, admitted that he may not reprise the role in the follow-up.
"I don't know, and that really is the honest answer. I know I've been known for obfuscation in other quarters, but I have no idea," he said.
