Downton Abbey star Jim Carter has described the connection between the cast of the epic period drama franchise as "unbreakable". Joining his co-stars Phyllis Logan, Raquel Cassidy and Kevin Doyle, the 77-year-old actor, who has portrayed loyal butler Mr Carson since the series began on ITV in 2015, spoke to HELLO! in an exclusive interview ahead of the premiere of the third film, Downton Abbey: The Grand Finale , which marks the end of the period drama after 15 years.

When asked about the friendships formed between cast members over the years, Jim said: "It is very rare in TV and film because it's filmed so separately, but we know that in ten years' time, if we bump into each other, that 15-year connection is unbreakable."
