The original cast of The Hitchhiker's Guide To The Galaxy have returned to the theatre where they created the show more than 30 years ago for a one-off performance.

The show began on radio in 1978 before becoming a hit Tv programme, series of books and a Hollywood movie.

Simon Jones, who played hapless hero Arthur Dent in the 1980s Tv series as well as in the long-running Bbc radio show, reprised his role for the special live radio broadcast.

Also returning were Mark Wing-Davey, who played the two-headed Zaphod, Geoff MCGivern as undercover alien Ford Prefect and Stephen Moore as Marvin the Paranoid Android.

The special radio show was performed live at London's Broadcasting House Radio Theatre on Saturday (29Mar14) and simultaneously aired on Bbc Radio 4.
