Halle Berry thinks there are more important things in life than being beautiful.

The actress, who is considered to be one of Hollywood's most stunning stars, plays a pregnant astronaut in the CBS sci-fi thriller 'Extant' and her co-stars claim she is beautiful inside and out, although she feels looks aren't everything.

She told Entertainment Tonight: ''Beauty is as beauty does. And I think it's how we live our lives, and how we treat people that really matters and really makes us beautiful human beings. And that's not about how we physically look, it's about how we do life.''

Halle's co-star Goran Visnjic, who plays her husband in the show, felt it was a ''blessing'' to work with the 47-year-old star and insists it was easy because she was always incredibly professional.

He said: ''She's always on time, and she's prepared and ready. But [also] the things like generosity towards everybody on a set.''

Camryn Manheim, who plays Halle's doctor on the show, also gushed about the brunette beauty.

She said: ''In my lifetime, I have never worked with somebody more gracious, more thoughtful, more intuitive, more fearless and more graceful than Halle Berry.

''You think she's beautiful because of her outside, but I know she's beautiful, magnified by a million percent, from what's coming from within. She is spectacular.''
