Showrunner Steven Moffat has said he doesn’t want any kind of crossover between Sherlock and Doctor Who, but Matt Smith has other ideas. When asked about the crossover, Smith said, “I’m not averse to it. I’m kind of open. I’m like yeah, because I just think they would find each other so remarkable.” As interesting as the concept may be to fans and Matt Smith, as long as Moffat sees it differently it’s not likely to happen. The closest we may ever come is this puppet version of The Doctor visiting Baker Street.
What do you think? Is the crossover a good idea, or would it be a wibbly-wobbly mess?
