The 33-year-old actor, who became famous after starring in 'Thor', said he did not believe director Kenneth Branagh when he told him to prepare for the fame that would follow him, reported Contactmusic.
"I never expected it. Fame is weird and amorphous and unpredictable. All acting is for an audience. It's just that my audience now is ... Quite large," he said.
"At the end of the shooting 'Thor' Kenneth Branagh took Chris Hemsworth and myself aside and said, 'In 12 months, boys, prepare yourselves!' We were both just, 'Nah!' We couldn't imagine it," Hiddleston said.
"Some people have been a bit obsessive about attributing responsibility for things that have happened in their lives to me. You can to say, 'Bless you for saying those nice things, but I've done nothing.' You sort of have to talk them off the ledge a bit. But that's the nature of obsession. I know a lot of other actors who've dealt with it," he added.
