Benedict Cumberbatch's sexiness questioned

This one is going to be a mystery for Benedict Cumberbatch fans.

According to Radio Times, a UK entertainment publication, the BBC didn't think the actor was sexy enough to play the role of Sherlock Holmes.

The publication reports that Steven Moffat, showrunner for both "Sherlock Holmes" and "Doctor Who," said at the Hay Festival that the BBC initially had concerns that Cumberbatch wouldn't bring the heat needed to play the classic detective. The network also worried over casting David Tennant in his role on "Casanova."

"They said of casting David Tennant as Casanova, 'Damn, you should have cast someone sexier.' With Benedict Cumberbatch, we were told the same thing. 'You promised us a sexy Sherlock, not him,' " Moffat said.

Such news is probably met with a resounding gasp from fans that have come to love Cumberbatch, not only from TV, but also from his success in films like "Star Trek Into Darkness." So guess who got the last, sexy laugh?
