Trigger Happy starred Ian Hart and Christine Tremarco and marked Gunn’s departure from making short films.
Following the success of these films Gunn went on to collaborate with Smack the Pony producer Victoria Pile on the pilot episode of the cult drama sit-com Green Wing.
Although uncredited, Gunn directed numerous scenes in the first episode (Caroline’s First Day) and co-created the visual and editorial style of the show.
Gunn also directed the feature-length adaptation of David Almond’s Clay for BBC 1, starring Oscar nominee and BAFTA award-winner Imelda Staunton.
In 2008 Gunn continued to direct high-concept-high-profile productions, most recently two of the opening episodes of Survivors, the BBC’s eagerly anticipated re-make of the 1970s cult science fiction drama starring Julie Graham and Max Beesley.
