Martin Freeman says the next series of Sherlock will be on TV at Christmas.
The actor - who plays Watson in the series - says he's filming now alongside Benedict Cumberbatch.
Season 4 of the hit show will once again be only 3 episodes long. Producers of the show have previously defended having a small number of episodes in each series, pointing out that each edition is an hour and a half long.

Speaking on the Graham Norton Show, Martin Freeman said “We are back filming now and the three shows will, I imagine, be out around Christmas".
He also spoke about the number of fans - many of them Cumberbitches - that turn up on set "There is always a heightened state of excitement and we sometimes have to respectfully remind them that we have to be focused and it’s not a live gig!”
It begins... Filming for series 4 is underway! #221Back @markgatisshttps://t.co/QeAiD1nza0
