The actor, 52 - who plays benevolent Robert Crawley, Earl of Grantham, in the hugely popular ITV series - told The Sun that the stars were frisked by production staff on the final day of filming... Incase they had stolen anything from the set!
Hugh admitted that strict security meant that "production were checking our pockets that we weren't stealing anything".
We don't think the Crawley family would have allowed such a thing!
Meanwhile, Jim Carter - who plays stern butler Carson - told the newspaper that the show will NOT end in tragedy like the 2012 Christmas special when Matthew Crawley died, leaving wife Mary a widow.
He says: "It doesn't end in a great big explosion, or a car crash. The story ends with people heading off in different directions on their life's journey, with hope and romance."
He adds that viewers will "be crying by the end of it".
On Wednesday (23 December), Michelle Dockery (who plays icy Mary) spoke to Good Morning Britain's Richard Arnold saying: "There's still lots of twists and turns in the special and I think the audience will be sad, but it ends on a positive note."
The pre-recorded interview was filmed on set before her very own tragedy this month... Her fiancé John Dineen died two weeks ago from 'a rare form of cancer'.
A statement from the Dockery family to The Mirror read: "The family is very grateful for the support and kindness they have received but would kindly request that they are left to grieve in private."
The last ever episode of Downton Abbey will air on Christmas Day, after five successful years on screen.
