The final ballot slips for this year's Oscars are due at the offices of accountants PricewaterhouseCoopers tonight (1700 PST Tuesday/0100 GMT Wednesday).
It will be five days before the stars learn the results of what has been one of the most fiercely fought contents in recent years.
Predictions put Russell Crowe and Denzel Washington neck and neck for the best actor award.
Amidst rumours of a campaign against Ron Howard's 'A Beautiful Mind' it is thought that fantasy epic 'Lord of the Rings: The Fellowship of the Ring' may be in with a chance for the Best Film Oscar.
The Oscars ceremony takes place on Sunday 24 March.
