Doctor Who fans will be able to see back-to-back episodes of rediscovered archive shows at a marathon screening later this month.
Devotees can see a dozen 25-minute episodes of the programme dating from the 1960s at the special showing which will also feature appearances from members of the cast, as well as a relative of the then Doctor Patrick Troughton.
The two stories, The Enemy Of The World and The Web Of Fear, will be screened on February 22 at the Prince Charles Cinema in London.
Nine of the episodes from these classic stories were missing and feared lost forever before they were returned to the BBC last year. They have since been restored and were released for download by BBC Worldwide
The Enemy Of The World has also been released on DVD, and The Web Of Fear will come out on February 24 in the format. Both stories date from the fifth season of the show and were screened in late 1967 and early 1968.
Fiona Eastwood, director of consumer products at BBC Worldwide, said: "The recovery of these missing stories was undoubtedly a high point for BBC Worldwide and Doctor Who fans around the world last year, and we hope there will be more to come.
"We're delighted that we've been able to make both of these stories available and the marathon screening at the Prince Charles Cinema is a great moment for Doctor Who fans to come together and celebrate their recovery."
