Harvey Weinstein has revealed that Grace Of Monaco was pushed back because it is not ready.
Olivier Dahan's upcoming film, which stars Nicole Kidman as actress-turned-princess Grace Kelly, has been delayed to 2014, months after its initial planned release in November, which would have made it eligible for the 2014 Oscars race.
The movie mogul admitted to The Hollywood Reporter: "The only reason is because it just wasn't ready. The score wasn't ready, a lot of things weren't ready.
"Also we've played no festivals on that movie, so it's hard to get into an Oscar race without at least some festival exposure," he added.
Tim Roth plays Rainier III, Prince of Monaco, with Derek Jacobi and Frank Langella in supporting roles.
Harvey continued: "The movie is going to be fantastic, and very glamorous. I think this could be bigger than My Week With Marilyn and in the same category of classy, intelligent filmmaking."
The co-founder of The Weinstein Company also said that the 2014 Oscars is hotting up to be "the most competitive season" he had ever seen.
Their slate includes Lee Daniels' The Butler, Mandela: Long Walk To Freedom, August: Osage County and Stephen Frears' Philomena, starring Dame Judi Dench, which are all considered to be strong contenders.
"This is the most competitive season I've ever seen. And if you aren't ready, don't get in it," Harvey said.
Other films which have also been delayed for the Oscars season include Foxcatcher, starring Steve Carell and Channing Tatum, and Martin Scorsese's The Wolf Of Wall Street with Leonardo DiCaprio.
