Alan Bennett's 1999 play The Lady in the Van is about a real life woman who lived in a camper van on Bennett's driveway for 15 years.
But now the stage show is being made into a feature film - with Harry Potter star Maggie Smith reprising her role as the homeless Miss Shepherd - RadioTimes.com understands that the playwright is ready to allow his real home to be used in the film.
Situated in Gloucester Crescent in Camden Town, north London, Bennett Towers, which the writer shares with his partner Rupert Thomas is very distinctive.
"Any other location would be immediately spotted by Bennett cognoscenti," according to a source on the film where the part of Bennett is being played by Alex Jennings.
Asked whether the location will be as bona fide as hoped, head of BBC Films Christine Langan told RadioTimes.com: “I think it’ll be very authentic, let’s put it like that.”
When asked if that meant Bennett's own home will be used she added: “Well, I can’t really reveal those kinds of details, sort of, now, but I think it will feel like ... it’ll feel very much like the real thing.”
Sir Nicholas Hytner will direct the film having also directed the first stage production in 1999.
