30 Seconds To Mars’ Jared Leto is a leading contender for best supporting actor Oscar

Leto is 10/1 to win for his performance as a transsexual woman in 'Dallas Buyers Club'

Jared Leto is a leading contender for next year’s best supporting actor Oscar, according to the latest odds from bookmakers.

The 30 Seconds To Mars frontman is gathering awards buzz for his performance in Dallas Buyers Club, a film inspired by the real-life story of Rod Woodroof, a Texan electrician diagnosed with HIV/AIDS in 1986 who began smuggling alternative drugs into America to help himself and other AIDS patients.

Matthew McConaughey stars as Woodroof, while Leto plays Rayon, a transsexual woman with HIV who helps him import the illegal medication. Both actors lost a considerable amount of weight for their roles – watch the trailer below.

Leto is currently 3/1 to receive a best supporting actor nomination for next year’s Oscars, which take place on March 2, 2014, and 10/1 to take home the gong on the night, bookmakers William Hill have confirmed. That makes him fourth favourite to win behind Michael Fassbender, 9/4 favourite for his performance in 12 Years A Slave, Tom Hanks, 11/4 for Captain Phillips and John Goodman, 11/2 for Inside Llewyn Davis.

A William Hill spokesperson told NME: “Leto has not really been on our screens so much in an acting capacity recently, so it is great to see him back and at his best. There is every chance that he could walk away with an Oscar for this performance.”

Leto makes his first film appearance since 2009 in Dallas Buyers Club as in recent years he has concentrated on touring and recording with 30 Seconds To Mars, who released their fourth album ‘Love, Lust, Faith And Dreams’ in May of this year (2013). Leto rose to prominence in ’90s teen TV series My So-Called Life opposite Claire Danes and later appeared in films including in Requiem For A Dream, Fight Club and American Psycho.
