The Crystal Cube was a mockumentary television pilot written by and starring Stephen Fry and Hugh Laurie, broadcast on 7 July 1983 on BBC2 at 22:10. The pilot was one of Fry and Laurie's first television appearances and the first show they had written themselves. However, the BBC chose not to take it to a full series, and Fry and Laurie did not get a chance to make their own programme for the BBC until 1989, when they produced their first full series of the more conventional sketch show A Bit of Fry and Laurie, after a pilot in 1987.
