Colin Firth is apparently set to appear in a sequel to The King's Speech.

The 52-year-old star, who scooped a Best Actor Oscar for his portrayal of King George VI in the 2010 historical drama, has agreed to reprise the role for a follow-up set during the Blitz, reports The Sun.

The film is apparently in the "very early stages" but if it does go ahead it seems Colin's co-stars Helena Bonham Carter and Geoffrey Rush are also likely to return.

A source said: "The sequel is going to be about the experience of families during the Blitz. It will focus on how the privileged Royal Family was hit by the crisis, compared to the more ordinary family of George VI's speech therapist.

"The focus will be on George but it will also show how the whole royal household was affected. There's still amazing interest in the Blitz. The movie is still in the very early stages but everyone's keen to get going soon."

In the first film, directed by Tom Hooper, Helena played George's wife Queen Elizabeth and Geoffrey starred as the king's speech therapist. It scooped four Academy Awards - Best Picture, Best Director, Best Actor and Best Original Screenplay.
