Jennifer Lawrence has won a lead-actress Golden Globe for the oddball romance "Silver Linings Playbook," while supporting-acting prizes went to Christoph Waltz for the slave-revenge tale "Django Unchained" and Anne Hathaway for the musical "Les Miserables."

The wins on Sunday firm up their prospects for Hollywood's top honors at the Feb. 24 Academy Awards.

Former President Bill Clinton upstaged Hollywood's elite with a surprise appearance to introduce Steven Spielberg's Civil War epic "Lincoln," which was up for best drama. The film chronicles Abraham Lincoln's final months as he tries to end the war and find common ground in a divided Congress to pass the 13th Amendment abolishing slavery.

Lincoln's effort was "forged in a cauldron of both principle and compromise," Clinton said. "This brilliant film shows us how he did it and gives us hope that we can do it again."

Amy Poehler, co-host of the Globes with Tina Fey, gushed afterward, "Wow, what an exciting special guest! That was Hillary Clinton's husband!"

Lawrence won as best actress in a musical or comedy for her role as a troubled widow in a shaky new relationship. The Globe winners in musical or comedy categories often aren't factors at the Oscars, which tend to favor heavier dramatic roles.

But "Silver Linings Playbook" is a crowd-pleasing comic drama.
