Jared Leto is on a roll.

A day after receiving a Screen Actors Guild nomination for his portrayal of an HIV-positive, transgender drug addict in "Dallas Buyers Club," the 41-year-old actor picked up a Golden Globe best supporting actor nomination.

"I'm so happy!" Leto told People. "I haven't made a film in almost six years and to return to this kind of enthusiastic support is absolutely insane."

Instead, Leto, who is currently on tour with his rock band band Thirty Seconds to Mars, has focused on his music. Critics have hailed his return to the screen playing opposite fellow Golden Globe nominee Matthew McConaughey, and Leto is widely expected to pick up an Oscar nomination too.

Asked if he had any good luck charms this award season, he joked, "I have a lock of Daniel Day-Lewis's hair and Marlon Brando's toenails as my good-luck charms."

"I'm just happy to be a part of this celebration," he told People on a more serious note. "It's been a journey, and the best thing about the nomination is it shines a light on this little movie. I'm just the ambassador, and it's an honor."

For Leto, who began his career on the TV series " My So Called Life," acting is now secondary. He recently told ABC News that he has no new movies in the pipeline.

"I don't know how long it's going to be till I make another one," he said.
