Martin Freeman has revealed the next series of Sherlock will be full of surprises and "so exciting".
The actor - who scooped the gong for outstanding supporting actor in a miniseries or a movie for his role as Dr John Watson at the Emmy's earlier this week - teased in an interview with BBC Radio Wales that he has been told "a bit" about the fourth series by writers Steven Moffat and Mark Gatiss.
Martin revealed: "It's going to be full of surprises for you, and for us and for everybody.
"I think we just know to expect the unexpected now.
"What has been explained to me and Ben [Cumberbatch] and Amanda Abbington - my missus who plays Mary - has been very exciting. The plans they have got for the overarching series - oh man, it's just so exciting!"
The final episode of series three, The Last Vow, saw the shock return of Sherlock's nemesis Moriarty (Andrew Scott).
Martin, 42, - who was also nominated for outstanding lead actor in a miniseries or a movie for his role in the TV adaptation of Fargo at the Emmys - did not attend the ceremony as he admitted he had not expected to win.
Sherlock actually won three awards in total - with Benedict being named outstanding lead actor in a miniseries and Steven taking home the outstanding writing in a miniseries gong.
Martin said: "It keeps going from strength to strength really, we're all very proud of it, we're all very pleased to be in it and involved in it, I think as a nation it's one of the UK's finest exports."
