NEW YORK: Actor Liev Schreiber has advised US President George W Bush on controlling his facial expression while giving speeches.

Pagesix.com quoted Schreiber as saying, "I'm a pretty liberal guy, but I had this daydream, this dream of helping Bush. I think I could help him be cooler."

"I think he's working the alpha-male thing a little too hard, and I think his eyebrows are getting stuck. So then, when he wants to switch to a light note, it's kind of hard, because the mouth goes but the eyebrows don't. You don't trust someone whose eyebrows don't move in unison with their mouth."
