Sylvester Stallone is to star in another Rambo movie, according to reports.

The 63-year-old actor is set to reprise his role as Vietnam veteran John Rambo for the fifth time next year in a film which will see his character battling drug and people traffickers on the US-Mexico border, says variety.com.

Rambo, which was released in 2008, had initially been billed as the final instalment in the series.

A source said: "The character obviously fascinates Sylvester and he feels there's more life in him yet.

"This time Rambo will be taking on drug lords and human traffickers after the kidnap of a young girl. Like all the previous films it's bound to be very violent but the character always had big box-office appeal."

Although the actor – who first played John Rambo in 1982's First Blood – is keen to begin production on the movie, he first faces a battle to get in shape.

The source added: "Sylvester really had to push himself to get in shape for the last film and knows he'll have to do that again for the next movie. It doesn't get any easier, the older he gets."
