The drama’s big-screen debut comes more than two years since the final TV episode of the ITV series, which attracted audiences of over 12 million in the UK.

It was regularly watched by 10 million in the US, despite airing on an non-mainstream channel.

A source said: “Film bosses have requested the services of crew members and accountants to work on the picture.

“A budget has been set and now it’s a case of getting everything in place to start shooting.

“It would take something big to stop the project from happening now.”

Speaking earlier this year, he said: “ I don’t want to be caught out if the producers suddenly say yes and then it’s all go.”

However, he did raise some concerns in regards to whether all the drama’s biggest stars, including Hugh Bonneville and Laura Carmichael, would be available to film at the same time.

Also, veteran actress Dame Maggie Smith, who plays the Dowager Countess of Grantham, also questioned if a film version would work, claiming writers had already been “squeezing the plot dry” over the six series, which have featured a total of 52 episodes.

During an on-stage interview at the British Film Institute last month, she said: “They talk about there being a film but who knows. I hope you might tell me if you do know.

“I just think it’s squeezing it dry, do you know what I mean? I don’t know what it could possibly be. It’s too meandering.”

The 2015 Christmas special and series finale saw Edith Crawley marry Bertie Pelham and Anna Bates give birth to a baby boy.
