Don't panic! The cast of the new Dad's Army movie are ready for duty as the latest image released from the film shows.

Toby Jones and Bill Nighy star as Captain Mainwaring and Sergeant Wilson in the big-screen adaptation of the BBC sitcom, due to be marched out in cinemas in February.

Danny Mays plays ladies man and wheeler dealer Private Walker, Michael Gambon takes on the role of frail Private Godfrey, The Inbetweeners' Blake Harrison will play confused Private Pike, Tom Courtenay is the excitable Corporal Jones and Bill Paterson will appear as pessimist Private Fraser.

The adventure, set in 1944, sees the Home Guard unit on a mission to patrol Dover Army base until they discover a radio signal sent direct to Berlin from Walmington-on-Sea, sparking rumours there could be a spy on the loose.

Filming began last year in the East Yorkshire seaside town of Bridlington, which will double for Walmington-on-Sea in the movie.

Catherine Zeta-Jones will play glamorous journalist Rose Winters, who arrives in the town to profile the brave soldiers keeping Great Britain safe.

Ian Lavender, who originally portrayed Private Pike, is set to make a cameo appearance in the film, with Mark Gatiss, Sarah Lancashire and Alison Steadman also among the cast.

Oliver Parker is directing the film, which will be released on February 5.
