Melissa Leo and Christian Bale garnered supporting actress and actor Oscars for their work, respectively.

Melissa Leo, 50, who already had Golden Globe and Screen Actors Guild wins under her belt for her work in boxing flick "The Fighter," still was virtually speechless when she accepted the Oscar for supporting actress.

"Oh, wow. Really, really, really, really, really truly wow," a visibly moving Leo said on stage at the Kodak Theater. "I know there's a lot of people that said a lot of real real nice things to me for several months now, but I'm just shaking in my boots here."

"I want to thank the very most of all, the Academy of Motion Picture Sciences, the Board of Governors, and all their members, whom many of you are here today," she said. "This has been a extraordinary journey in getting to know what the Academy is about and first and foremost, thank you Academy, because it's about selling motion pictures and respecting the work!"

The actress, who won her first Oscar, thanked Alice Ward, the boxing-family matriarch she portrayed in the film, and the entire Ward family, "for opening your hearts to all of us to make this film."

Leo previously got a nod for best actress for "Frozen River" in 2008.

Bale, 37, landed his first Oscar after he was nominated for the honor. He also had Golden Globe and SAG award wins for his role as Dicky Eklund in the gritty movie.

"Bloody hell. What a room full of talented and inspirational people, and what the hell am I doing in the midst of you," he said. "It's such an honor."

Bale, who has a reputation as a sometimes hot-headed co-worker and who was caught on tape verbally berating a crew member on the set of "Terminator Salvation," joked that he would not use the "F-bomb" like Leo did during her acceptance speech.

"I've done that plenty before," he said.
