Leonardo DiCaprio sent girls swooning in Titanic, swaggered as The Wolf of Wall Street, and creeped audiences out as reclusive billionaire Howard Hughes. But it took a seven-month, sub-zero shoot, and a role in which he barely speaks, to give him his best shot at finally winning an Oscar.DiCaprio, 41, and still a bachelor, received his fifth Oscar nod yesterday, this time for his lead role in The Revenant.The pioneer-era revenge drama led all contenders with 12 nominations.DiCaprio plays Hugh Glass, a taciturn, greasy-haired 1820s fur trapper left for dead in the wilderness by his own hunting team after being mauled by a bear that rips his throat.In a fight for survival, Glass treks through snow-covered forests, gets swept away in a waterfall, sleeps inside the carcass of a disembowelled horse and hungrily eats raw bison liver before making it back to his camp.DiCaprio has already won a Golden Globe for the role and he tops pundits' forecasts to take home the best actor Oscar at the Academy Awards."I think his performance has to be seen by, I hope, millions of people [and] I'm sure they will be emotionally involved and happy about seeing Leo in this [role]," Alejandro G Inarritu, the director of The Revenant, said.DiCaprio has been nominated alongside Bryan Cranston for Trumbo, Matt Damon for The Martian, Michael Fassbender for Steve Jobs and Eddie Redmayne for The Danish Girl.South Africa's Oscar winner, Charlize Theron, has congratulated her colleagues in the cast of Mad Max: Fury Road for their 10 Academy Award nominations, including for best picture."It's heart-warming to see all the love streaming in!" she tweeted. ..
