Collinson worked in theater and on television commercials before helming his first feature in 1967, the thriller The Penthouse, which he also scripted. Collinson went on to do some of his best work in the late '60s: Up the Junction, the World War II drama The Long Day's Dying, and the caper spoof The Italian Job. His later work covers a range of genres, including comedy (You Can't Win 'Em All) thrillers (Fright, Straight on Till Morning), and the Agatha Christie mystery And Then There Were None (aka Ten Little Indians). ~ All Movie Guide
