George Clooney Is Almost Unrecognizable Without His Signature Silver Hair — See His Brunet Transformation!

George Clooney has a new look!

The actor, 63, revealed a shocking transformation, ditching his signature silver hair for a new brunet style. On Saturday, March 9, Clooney was spotted in the SoHo neighborhood of New York City sporting a medium brown shade.

He also wore off-white chinos, a black leather jacket, Adidas sneakers and sunglasses.

The star's dramatic new look is for his Broadway debut in Good Night, and Good Luck, which begins previews on Wednesday, March 12, at N.Y.C.'s Winter Garden Theatre ahead of an opening night of Thursday, April 3.

The play, co-written by and co-starring Grant Heslov, is a stage adaptation of the 2005 film. Clooney and Heslov co-wrote the play together after collaborating on the screenwriting of the original film, about CBS news journalist Edward R. Murrow's legendary exposé on Senator Joseph McCarthy.

In the film, Clooney played news producer Fred Friendly. But in the Broadway production, he'll portray Murrow, the role that earned David Strathairn a 2006 Oscar nomination.

During an appearance on The Late Show with Stephen Colbert on Tuesday, Feb. 18, Clooney said that despite co-writing the film and the play, memorizing his lines for the Broadway show has been "a nightmare."

"I don't remember my kids' names!" joked Clooney, who shares 7-year-old twins Alexander and Ella with wife Amal. "I'm 63!"

"It's weird. When I did ER, we'd do 12 pages a day of medical dialogue and you could just come in and whip it out. I was 30 years [old]," Clooney continued. He then demonstrated his recall of the phrase "supraventricular tachycardia," which he said he's "never gotten wrong since" doing the 1994 drama. "Now I can't remember anything," he added.
