Jared Leto on his award-winning role in Dallas Buyers Club

Jared Leto says it was the script - not prizes - which encouraged him to take on the role of an HIV positive transgendered woman in the critically-acclaimed Dallas Buyers Club.

The actor has already been awarded with a Golden Globe and Screen Actors Guild Award, and Leto has also been nominated for the best actor in a supporting role category at the Oscars.

But he told the BBC's Lizo Mzimba that getting the character of Rayon right on screen was always his main aim.
