His followers were quick to comment, with one writing: "Didn’t recognise you at first," while another added: "My, you've lost some weight, good for you!" However, a third person was a little concerned, writing: "Oh Hugh, I do hope you are well; the weight loss doesn't suit you at all."
Hugh will be reprising his role as Lord Grantham in the sequel movie, which is set to be released in March 2022. Downton Abbey's official Twitter account previously announced that some new faces would be joining the cast. The tweet read: "We're thrilled to announce that Julian Fellowes and the entire Downton cast are back for #DowntonAbbey2, with Hugh Dancy, Laura Haddock, Nathalie Baye and Dominic West joining! See the film in theatres this Christmas."
Fans commented on Hugh's weight transformation
The Paddington star also shared a snap of himself next to a poster of the film, writing: "Good to be back. #DowntonAbbey2."
Fans were understandably thrilled by the very exciting news, with one writing: "What???? A second Downton Abbey movie! OMG!! Yes!" Another added: "OMG Hugh Dancy!! I guess I'll finally be sitting down to watch Downton Abbey in preparation for this film!"
