Armchair Thriller is a British television programme, broadcast on ITV in two series in 1978 and 1980. Owing something to some of the off-shoots of the earlier Armchair Theatre, the new series used scripts adapted from published novels and stories. Although not properly a horror series it included several supernatural elements. Armchair Thriller was produced by Thames Television, but it included serials made by Southern Television. The format was of a twice weekly 25 minute episodes, usually screened on a Tuesday or Thursday at 20:00-21:00.
