American actor Brian Donlevy, supported by the English actor Jack Warner, with Val Guest directing and co-writing the screenplay. Nigel Kneale was unhappy with the result, and was especially displeased with the casting of Donlevy as Quatermass. He stated in an interview, "[Donlevy] was then really on the skids and didn't care what he was doing. He took very little interest in the making of the films or in playing the part. It was a case of take the money and run. Or in the case of Mr Donlevy, waddle." The film was titled The Quatermass Xperiment to emphasise its X-certificate status. In America the film was renamed The Creeping Unknown after the title Shock! was considered for that territory, and an alternative opening title sequence with that name was prepared. The BBC was also pleased with the success of The Quatermass Experiment and in 1955 a sequel, Quatermass II, was broadcast, with John Robinson in the title role following Tate's death. This was followed in 1958 by Quatermass and the Pit, and both serials also had feature film versions made by Hammer. The character returned to television in a 1979 serial, simply titled Quatermass, for Thames Television. A script book of The Quatermass Experiment, containing several production stills from the missing episodes, was published by Penguin Books in 1959. To coincide with the broadcast of the Thames serial, it was republished in 1979 with a new introduction by Kneale. In April 2005, BBC Worldwide released a boxed set of all their Quatermass material on DVD, containing digitally restored versions of the two existing episodes of The Quatermass Experiment, the two subsequent BBC serials, and various extra material, including PDF files of photocopies of the original scripts for episodes three to six. However, the quality of these photocopies is in some cases quite poor. The missing episodes were also semi-reconstructed using production stills, with subtitles to describe the actions depicted in the photographs. On 2 April 2005, the digital television channel BBC Four broadcast a live remake of the serial, abridged to a single special, also entitled The Quatermass Experiment''.
