The Academy of Motion Picture Arts and Sciences said it has extended voting for the 2013 Oscars, after reports of problems with a new online polling system.
The elite movie industry body is giving its voting members an extra day -- the deadline will be this Friday at 5:00 pm Los Angeles time (0100 GMT Saturday), instead of 24 hours earlier -- to choose their nominees.
"By extending the voting deadline we are providing every opportunity available to make the transition to online balloting as smooth as possible," Academy chief operating officer Ric Robertson said on Monday.
"We're grateful to our global membership for joining us in this process," he added in a statement.
The Academy, which organizes the climax to Hollywood's annual awards season in February, introduced the option of online voting for first time for its nearly 6,000 members.
Old-fashioned voting by mail was still possible, although an initial November 30 deadline for requesting the ballot papers had to be extended by two weeks after complaints from members that they had missed it.
The Academy also set up e-voting stations in Los Angeles, New York and London, where its own officials could help members through the process.
But reports of problems with online voting have snowballed, with some Academy members struggling with the security system of passwords required to register their choices.
"It's easier to break into the CIA," one member told the Hollywood Reporter last week, in a piece which said many voiced concern that many older voters would give up and not cast their ballots.
"You know, a lot of older, cantankerous people -- people who aren't so highly motivated to vote -- are going to say, 'Oh, forget this.' I'm sure there's going to be some votes lost," added another member.
The median age of the Academy's 5,765 members is 62, according to a recent study cited by the Hollywood Reporter.
Nominees will be announced at 5:00 am on January 10 (0100 GMT on January 11), while the winners will be announced on February 24, at a show hosted by "Family Guy" creator Seth MacFarlane.
Unlike in some previous years there is no clear favorite for best picture, with frontrunners ranging from Steven Spielberg's political drama "Lincoln" to Osama Bin Laden manhunt docu-thriller "Zero Dark Thirty."
Others tipped for Oscars glory include musical adaptation "Les Miserables," romcom "Silver Linings Playbook," Ang Lee's 3D fantasy "Life of Pi," and actor-director Ben Affleck's Iran hostage crisis drama "Argo."
