London, Sep 29 (IANS): Screenwriter Peter Morgan is working on a film with director Ang Lee about boxing legend Muhammad Ali.

The movie will be based on Ali's infamous fights with late US professional boxer Joe Frazier, reports femalefirst.co.uk.

The two boxers fought several historic bouts in the 1970s, and the film will be based around the confrontations between the two heavyweight champions.

Lee hopes to shoot the movie in 3D and incorporate actual footage of the fights.

"It's a look at how brutal the confrontations were between Ali and Frazier. They were marked by how aggressive Ali was towards Frazier out of the ring. He taunted and belittled him. Ang wants to work with 3D technology that will make an audience feel as if they're inside the ring," Morgan told British newspaper Daily Mail.

Morgan hopes to finish the script next year.

Ali's story was previously brought to the big screen by actor-producer Will Smith in 2001 biopic "Ali".
