Michelle Williams delivered a characteristically captivating performance as Marilyn Monroe in "My Week with Marilyn", and the awards circuit are taking notice.

The pixie-haired beauty will be honored at the Palm Springs International Film Festival (PSIFF) awards gala, along with fellow honorees George Clooney and Glenn Close.

She will be the recipient of the Desert Palm Achievement Actress Award.

In an official statement, PSIFF chairman Harold Matzner explains the decision to present Williams with the award.

"Every generation, the cinema has a few performers who mesmerize audiences with an exceptional blend of talent, versatility and grace," Matzner says in the press release.

"Michelle Williams epitomizes these qualities as she continues to accept challenging role after challenging role," he adds.

Another "victory" came when Williams figured out what she calls the bombshell's "real voice".

"I lived on people's compliments, kind words. An approving glance would last me for days," she confesses to Washington Post.

Perhaps the insecurity is a side effect of embodying the famously

Williams appears on the Simon Curtis film "My Week with Marilyn" in the starring role, alongside Kenneth Branagh and Eddie Redmayne. It is based on the journals of third assistant director Colin Clark, who spent seven days with Monroe touring the English countryside.
