Martin Clunes has threatened to ride onto the set of Downton Abbey - because his neighbour Julian Fellowes hasn't taken up his offer to appear in the drama. The Doc Martin star, who is known for his love of horses and plays a mayor in new ITV1 drama The Town, would love to have a spell in the period drama, according to The Sun. He joked: "Julian (Downton creator) is my neighbour. He lives just around the corner and I keep lobbying him but he won't. "I might just ride into an episode out of spite." A fourth series of Downton is due to return to ITV1 next year. This year's two-hour festive episode sees the family head to a Scottish estate - filmed at Inveraray Castle - to visit cousins, against a backdrop of deer stalking and shooting in the Highlands.
