Matt Smith has dismissed the hopes of fans that he could make an appearance in the BBC's popular Sherlock.

The recently departed Doctor Who star told the crowd at the Wizard World Comic Con that he doesn't think there's any space for him in Who showrunner Steven Moffat's other big show.

"Listen, there's no room for me on Sherlock!

"They've got Benedict and Martin, that's quite enough peculiar Englishmen for that show. There's no room for another."

Smith, 31, auditioned for the role of Watson in Sherlock - but the part went to Martin Freeman.

Meanwhile Freeman has been telling chat show host Alan Carr that he doesn't even know if Sherlock will be back for a fourth series.

"It's not only us two, it's Steven Moffat, Mark Gatiss, the writers and creators, we are all very busy. So in all honesty, and I'm not being cute here, I don't know," he stressed.

"I really, really don't know. Steven and Mark have a great idea for something we could do next... It's a fantastic, really mouth-watering idea.

"But I really don't know when we are going to get to do it. I'm up for it - I'm ready - but it's getting planes to land in order. We just all need to be ready at the same time."

The actor can be seen on Alan Carr Chatty Man on Channel 4 tomorrow evening.
