Actor-turned-filmmaker Ben Affleck won the top honor from his peers at the Directors Guild of America on Saturday for the movie "Argo", cementing the Iran hostage drama's frontrunner status for the Oscars.

The Hollywood directors' recognition for Affleck, however, is an awkward result for the Academy of Motion Pictures Arts and Sciences, which failed to nominate him for Best Director in what is considered one of the biggest snubs of this year's Oscars.

Since 1948, there have been only six occasions when the Directors Guild of America (DGA) winner has not gone on to win the Oscar for Best Director.

"I have nothing but respect for the Academy," Affleck said after collecting his first DGA award. The Hollywood star, a producer of "Argo", said he was thrilled the film was nominated for the Oscars' Best Picture award.

"You are not entitled to win anything," he said.

"Argo" has picked up the three top awards from the industry's guilds, whose members are also often members of the Academy.

Last weekend, the film was the victor at both the Producers Guild and the Screen Actors Guild awards, leaving Steven Spielberg's Civil War-era epic "Lincoln" in its wake.

Affleck also won Best Director at the Golden Globes while "Argo" won Best Drama. The Oscars will be held on February 24.
