Jared Leto has said that, while his Oscar has led to new opportunities in Hollywood, he is not overly concerned with the trophy itself.

The actor-musician took home the gold statuette last month for his supporting role as transgender drug addict Rayon in Dallas Buyers Club. It has since suffered a few scrapes after circulated among his friends.

"I damaged it. But then I came home and saw it had another nick on it. So it looks like someone else had fun with it, too," Leto said in an interview.

"My Oscar is a filthy mess. Everybody was pawing that thing. I kind of was just passing it around at parties. A couple of times I lost sight of it and I thought 'You know, if it goes away, it's not meant to be mine'. But it always seemed to find its way back to me."

Leto is now promoting Artifact, a documentary he directed about the battle that his band, 30 Seconds To Mars, had with its record label over its contract and a 30 million-dollar lawsuit.

The 42-year-old said his success with Buyers Club has renewed his interest in acting - partly because of renewed interest in him from top film-makers.

"Yeah, I'm looking at scripts and reading scripts. Which is interesting because I didn't read scripts for years before Dallas Buyers Club," he said. "But now... you have opportunities to work with people that you really respect or admire, people whose work has been inspiring and influential."

Leto has directed many of his band's music videos. He directed Artifact under the name Bartholomew Cubbins. And he is a prime example of the old actor cliche: What he really wants to do is direct features.

"I think that would be really great. And when I have the right story to tell I'll certainly do that," Leto said. "You know I got into this crazy business because I was interested in being a film-maker and director. I was in... art school studying to be a painter. And then I switched my major to film-making and dropped out to pursue acting because I thought it would help me get a job as a director."

There has been a surge of interest in 30 Seconds To Mars. Their last album, Love, Lust, Faith & Dreams, was released in May 2013 but jumped to number 25 on the Billboard charts after the Oscars ceremony. The band discounted it briefly and released a new single, Do Or Die.

Leto said he has not been strategically marketing the group to capitalise on his Hollywood momentum. But he acknowledges: "I mean it's hard to separate these things in my life. I can't manage to separate them - whether I'm director or editor or actor or musician or tech entrepreneur, I'm doing all kinds of things all the time. And I would go crazy if I tried to put a wall up in between them all."
