Judi Dench and Eddie Izzard look set to work together again on thriller Six Seconds to Midnight.
Dame Judi is in talks to join the cast of the film which is due to begin filming in Wales in June. Izzard has already been confirmed.
The story follows a teacher at an elite finishing school on the English coast who gets caught up in a Nazi conspiracy.
Izzard will play Thomas Miller, a literature and language teacher born to English and German parents who teaches members of the German League for Girls.
As the Second World War looms, Miller is framed for murder and accused of being a German spy after he confronts the League’s charismatic leader, a staunch supporter of Adolf Hitler.
Dench will portray Miss Rocholl, the stern school headmistress who comes to Miller’s aid after he goes on the run and attempts to exonerate himself.
The pair previously worked together on Victoria & Abdul.
