Sherlock crossover

WhoLock is a famous word in some parts of the Internet. It signifies the crossover between “Sherlock” and “Doctor Who,” a merger some fans are desperate to see come to life. With the recent revelation an episode of “Sherlock” will travel back to the Victorian era, it seems more likely than ever. “Sherlock” and “Doctor Who” executive producer Steven Moffat said he wants to do it for the fans -- but that doesn’t mean it’ll happen.

“My instinct -- and this is probably from years of doing ‘Doctor Who’ -- is I’m just such a tart. If people want to, we should give it to them,” Moffat told Entertainment Weekly.

It isn’t as if it’s completely impossible. Both air in the U.K. on BBC and Steven Moffat is in charge of both. Yet Moffat explained while fans are up for it, some of the people involved with the shows aren’t quite ready for a "Sherlock"/"Doctor Who" crossover.

“But I got persuaded by Mark [Gatiss], Benedict [Cumberbatch], [executive producer Sue Vertue] and Martin [Freeman] saying, ‘Look, it will never be as good as they think it’s going to be,’ and then I say, ‘Yes, but we’ll just bang it out and make it as good,’” Moffat explained. “‘Yeah, but you can’t give everybody everything they want all the time.’ I’m in the camp of giving them everything they want. But I think they’re sane and right, and I’m just a tart.”

Moffat previously gave a similar response when he was asked about a crossover in August. “You know in some ways, I think Mark [Gatiss] has got a point when he says that however good you imagine [the crossover], it would be almost better in your imagination than it would be if the two grand old egotists actually met,” Moffat told the Independent. “They’d just both go off in opposite corners and sulk that there was someone cleverer than them.”

It looks like a crossover won’t happen in “Doctor Who” Season 9 or “Sherlock” Season 4, but some fans certainly hope the actors and creative team will change their minds.

What do you think: Should Moffat stay away from an impossible task or should he do it for the fans? Take the poll below!

“Doctor Who” Season 9 will premiere on BBC America in the fall while a premiere date for “Sherlock” Season 4 has not been announced by PBS.
