All Creatures Great and Small fans, don’t fear. Despite Callum Woodhouse saying he was “done” in a Season 6 teaser shared by PBS earlier this week, the series has assured that he’s not leaving the show. The All Creatures Great and Small Season 6 cast list has just been revealed, and it confirms that he will be back as Tristan Farnon alongside his fellow longtime costars. It also reveals a time jump in Season 6 and a new baby for the Herriot family!

That August 19 behind-the-scenes video also made fans wonder why Anna Madeley (Mrs. Hall) wasn’t present, but she’ll be back in the new season. The August 21 announcement also came with the first photos from Season 6, set to premiere in 2026 in the U.S., and the announcement of five new cast members. It’s a busy day for fans of this heartwarming series.

All Creatures Great and Small Season 6 takes us back to the beautiful Yorkshire Dales for more heartwarming human and animal tales but, this time, we find our beloved Skeldale gang in a somewhat different situation as we join them in 1945, just as the war in Europe is coming to a close. We arrive back in Darrowby to veterinary advancements, expanded families, and new faces as they all look ahead to a brighter and more peaceful future. This season will see Herriot’s wonderful characters navigating the opportunities that a new world brings, a host of animals great and small, and of course, each other.

This marks a four-year time jump between Season 5 and 6. Season 5 was set in the spring of 1941.

Who is in the All Creatures Great and Small Season 6 cast?
