Independent Films have released the first trailer and poster for comedy-drama Third Star.

Directed by BAFTA Award-winning filmmaker Hattie Dalton, Third Star stars Hugh Bonneville, Tom Burke, Benedict Cumberbatch, JJ Feild, Rupert Frazer, Nia Roberts, Adam Robertson and Eros Vlahos.

James (Cumberbatch) and his three closest lifelong friends go on an ill-advised trip to the stunning coastal area of Barafundle Bay in West Wales. What follows is a touching and comical adventure dealing with friendship, heroism and love.

Third Star closed the 64th annual Edinburgh International Film Festival last year, and will be released nationwide on May 20.
