Fans of The Inbetweeners have British funnyman David Walliams to thank for the hit comedy - he allowed the show's writer to stay at his home free for a year while working on the series.

Iain Morris teamed up with his pal Damon Beesley to pen the show, using their own cringeworthy teenage experiences to inspire the antics of geeky schoolkids Simon, Neil, Jay and Will.

Now Morris reveals Little Britain star Walliams played a huge part in bringing the comedy to fruition, because he allowed him to lodge at his London home when he was down on his luck.

The writer tells BBC Radio 5, "That allowed me to write. Without David Walliams, and another friend who also let me stay for free for nine months, I probably wouldn't have been able to continue to try and write stuff."

The show won a cult following following its debut in 2008, spawning a U.S. adaptation and a movie spin-off, which holds the box office record for the most successful opening weekend for a comedy release in Britain. A big screen sequel is currently in the works.
