Mindhorn (2016)

Richard Thorncroft is a has-been British TV actor who used to be famous in the late 1980s for playing the charismatic lead role in the Isle of Man detective show Mindhorn, a character with a robotic eye that can literally "see the truth". Richard gets an unexpected opportunity to reignite his career by returning to the Island to solve a real-life crime.
