EastEnders bosses will shoot a back-up tape to play in case of a 'proper crisis' during the live episode. Executive producer Diederick Santer (pictured) said the tape will only be played if something goes 'seriously wrong' during the broadcast on Friday, February 19, which marks the soap's 25th anniversary. Diederick told Inside Soap magazine: "We'll be filming the rehearsal, including the various versions of the reveal scene - that way, if something goes seriously wrong, to which the only alternative is BBC1 going back, we can play the tape. "But we won't be using it if anyone just fluffs a line or missed a cue. In those cases, we'll power on using our improvisational skills. It's really just for technical back-up in case of a proper crisis." The soap's cast received their script for the episode last Friday, but so far only a handful of people know the identity of Archie Mitchell's killer. It is thought the actor or actress in question will only find out on the night of the broadcast itself. Click here to watch whatsontv.co.uk's weekly soaps video preview, the Soap Scoop
