London, Dec 18 : Despite its cast of relative unknowns, Danny Boyle''s `Slumdog Millionaire' has become this season''s buzz film and is now being tipped as a frontrunner for an Oscar.

`Slumdog Millionaire' is a fictitious story about an 18-year-old Indian, who wins India''s version of Who Wants To Be A Millionaire.

Shot on location in Mumbai before the terror attacks, the film has already charmed critics and Golden Globe voters, earning four nominations, including best director and picture.

Boyle couldn''t be happier with the industry recognition.

"You need it for a film like this because we don''t have huge stars in it, who are going to do all that automatic [promotion] work for us," Sky News quoted Boyle, as saying.

"We won''t command the front of magazines because we don''t have that kind of star in it. So you need other techniques and the award season - which we''re in at the moment and we''re benefiting from - is just invaluable, it''s priceless," Boyle added. (ANI)
