George Clooney is concerned that reviews of his next film will focus only on his appearance.

The actor received a makeover to look overweight and aged for his role as a CIA agent in Syriana.

However, Clooney is now worried that this will overshadow any constructive criticism of the movie.

"On Solaris, which I happen to think is a very interesting film, all anyone talked about was the few seconds of my naked butt," Breakingnews.ie quotes him as saying.

Explaining his decision to take on the role, George added, "There's only so many times I can play the leading man who gets the girl."
