Sylvester Stallone is said to be a huge fan of the forthcoming Son Of Rambow, a small British film in which two kids remake his Viet vet classic First Blood in the local woods armed with nothing more lethal than a video camera.

Garth Jennings, the film's director, told The Observer the Rambo star may even help to promote the movie.

"We don't know how well it'll translate to American audiences," says Jennings, "but we have a name many people will recognise and which may trick quite a few into thinking they're going to see a Stallone sequel and it looks like Sly's agreed to do some TV appearances for us."

Jennings had to approach the action hero for permission to use clips from Rambo in his film, which he described as a thrill in itself. "It was one of the great days of my life when I sat down to write a letter that began: Dear Mr Stallone," recalls Garth. "It was even more exciting to get a letter back granting us permission to use the clips we wanted."

Jennings has even offered to help out should Sly decide on yet another outing for hiss now rather elderly jungle warrior. Despite the pasting given to the latest Rambo, he thinks the problem wasn't too much bloodshed but not enough. "We'd certainly up the violence," says Garth. "The 243 dead bodies in the last one just weren't enough for me."
