George Clooney's The Monument's Men is out the Oscar race as the film is delayed for several month following CGI setbacks.

The World War II drama which the 52-year-old actor co-wrote, stars in and directs was set to be released this December, but a statement from Clooney given to the Los Angeles Times reveals that The Monuments Men won't hit cinemas until early 2014.

Clooney plays George Stout who leads a team of art historians, museum curators and academics in a race to rescue a number of priceless works of art looted by the Nazis during their rampage through Europe.

The screenplay was written by Clooney and Grant Heslov, who used the Robert Edsel account, The Monuments Men: Allied Heroes, Nazi Thieves, and the Greatest Treasure Hunt in History, to base the movie on.

Speaking earlier this week Clooney said : "We just didn't have enough time. If any of the effects looked cheesy, the whole movie would look cheesy. We simply don't have enough people to work enough hours to finish it."

The film's delay now means it can't be considered for nomination at the 2014 Academy Awards, however Clooney insists that Oscar glory had never been the main ambition of the film.

He said: "All we've ever said, from the very beginning, is that we wanted to make a commercial, non-cynical piece of entertainment, one that focuses on the ensemble cast, similar to The Guns of Navarone."

The film also stars Matt Damon, Bill Murray, John Goodman, Cate Blanchett, Jean Dujardin and Hugh Bonneville.
