The production will now be at the Playhouse until 26 September
The upcoming West End return of Richard O'Brien's The Rocky Horror Show has extended booking at the Playhouse Theatre by a further eight performances.
The show, starring O'Brien as the Narrator, was originally scheduled to run from 11 to 19 September 2015, but will now continue until 26 September.
O'Brien said: "The response to The Rocky Horror Show has been outstanding; we're delighted to be adding more dates to the run at The Playhouse. We are all really looking forward to being a part of these very special shows."
Producers have also announced that actor Anthony Head will join the line-up of the charity gala for Amnesty International on 17 September, which also features Stephen Fry, Mel Giedroyc and Emma Bunton.
