Luke Wiltshire, 17, who is living with the rare cancer Neuroblastoma, gets to meet Jason Buckley – Jay in the Channel 4 show – on the set of his new film The Comedians Guide to Survival.

Children’s charity Rays of Sunshine and Red Rock Entertainment Ltd, supporter of the charity, arrange for teenager, Luke, to meet James Buckley.

Luke, who is being treated at University College Hospital, is a big comedy fan and was delighted to visit the movie set with his best friend Jake from Ealing, who has stood by him throughout his illness.

Diagnosed in 2012, Luke has undergone extensive treatment including chemotherapy, radiotherapy, surgery and stem cell rescue.

However, he has now been told there is no further treatment available to him in the UK.

James’s new film is directed by Mark Murphy and produced by Red Rock Entertainment, which is based at Elstree Studios in Borehamwood.

It sees James take on the role of James Mullinger to tell the true story of his journey around the world to discover the secret of comedy.

Luke was able to enjoy an exclusive behind-the-scenes view of the film set, before spending time with James during a break in filming.

He said afterwards: “James was so down to earth, just like his character Jay from the Inbetweeners.

“It was great to be able to hang out on set and hear some industry secrets. Thanks again to Rays of Sunshine and Red Rock Entertainment for inviting me down for such a great day.”

Rays of Sunshine Children’s Charity exists to “brighten up the lives” of seriously ill children in the UK aged three to 18 by granting wishes, organising outings and large scale events.
