British actor Benedict Cumberbatch fears that he may have overexposed himself by accepting too many parts.

The 37-year-old has recently appeared in BBC drama Sherlock,  as well as films such as 12 Years a SlaveStar Trek Into Darkness and The Hobbit: The Desolation of Smaug.

Speaking to Adelaide's The Advertiser, he said: "I'd hate to think anyone is sick of the sight of me, although I wouldn't blame them. It's just crazy. I've overexposed myself! Actually that sounds a bit dirty."

Cumberbatch added that he trades off that potential overexposure by taking a varied selection of roles.

"I'm proud of every single project," he insists. "I can genuinely say that it is varied enough, as a slate, to not fear too much overexposure. I just hope the public agree because they are seeing a lot of me.

"It would be really churlish to complain about anything to be honest. I'm very fortunate to be in the position I'm in."
