Ricky Gervais, writer and star of BBC sitcoms The Office and Extras, is starring in a cinema trailer for children's charity the Variety Club.
The 20-second trailer will be broadcast throughout February in cinemas across the country to increase awareness of the charity, which supports sick, disabled and disadvantaged children. It is also designed to encourage people to join its Friends of Variety scheme.
Gervais stars alongside children from the Bridge School in north London. The charity has worked with the school, which teaches children with learning disabilities, for several years.
"In the past few years, I've seen the difference the Variety Club makes to disadvantaged children," says Gervais. "Making the trailer was a great laugh and I hope the kids from the Bridge School enjoyed it as much as I did."

Singer Charlotte Church became a patron of the Topsy Foundation last year. The charity offers relief, care, medical and support services to people living with HIV and Aids in rural communities in South Africa.
"After Charlotte made a donation, we approached her with a request to become patron," says Sian Venturotti, development manager at the foundation. "We knew through her financial support that the issue of HIV and Aids, in particular how it affects families, was one she greatly sympathised with.
"We were looking to raise our profile in the UK and felt that she would help us achieve this. At the time, Charlotte was preparing to start a family of her own and expressed a desire to help others in less privileged circumstances."
To date, Church has talked about the work of the foundation in her press interviews and on her website. She says: "It's an honour to be involved with the foundation. It brings genuine benefit to people affected by HIV and Aids."
