George Clooney is a giga-star. An Academy Award victor. The man women desire and men desire to be. But for sheer, ear-piercing squeals, he’s no Robert Pattinson.

Anna Kendrick should know. The 24-year-old actress has been in the rare — and, for many females, enviable — position of having worked alongside both actors.

Even as she swung through the Toronto International Film Festival to promote Clooney’s Up In The Air, she was preparing to wrap work in Vancouver on the second Twilight sequel, Eclipse, in which she reprises the role she originated in 2008’s phenom. The first sequel, New Moon, opens in November, weeks ahead of Up In The Air.

“I’ve never seen anything like it in my life,” she says of the hysteria surrounding Pattinson, who stars as the Twilight’s brooding blood-slurper Edward. “People were asking me ‘Can you believe how crazy this premiere (for Up In The Air) is?’ And I was like, ‘You ain’t seen nothing.’ Most people have never seen anything like the Rob Pattinson phenomenon.”

How do the two leading men, albeit of different generations, compare?

“They get different sides of it. Rob gets a lot of screaming and a lot of prying and a lot of intensity, which doesn’t necessarily feel good when it comes from a hysterical place. And then I see people talk to George, because he’s so established, people try to trick him into saying something and it’s interesting watching him sidestep that stuff so gracefully and never lose his cool; I don’t know how he does it.”

In the dramatic comedy, Clooney and Kendrick are professional adversaries who embark on a cross-country odyssey of self-awakening. Alone on the road with Clooney? Somehow her character doesn’t develop a crush on him. But did Kendrick during filming?

“I think we have a more father-daughter relationship in the film. I think we almost cultivated that relationship in real life too. George at one point set an age limit for boys I was allowed to date, so it was not a crush on George Clooney kind of situation.”

What was the age limit?

“It was something really random, I can’t remember. You know what?” she says, beaming.

“Age doesn’t matter to me — and he’s not really my dad, so he can’t tell me what to do.”
