Los Angeles, July 21 (AP): Uma Thurman (in picture) is known for playing extreme characters.

As Mia Wallace in Pulp Fiction, a performance that earned her an Oscar nomination, she accidentally snorts heroin and ends up with an adrenaline shot in the chest.

In the two Kill Bill films, she plays a sword-wielding bride hell-bent on revenge.

She’s also been a bisexual hippie hitchhiker, a virginal 18th-century convent girl and the goddess Venus.

In her latest film ? My Super Ex-Girlfriend, opening today in the US ? Thurman plays two extremes at once.

She is Jenny Johnson, a neurotic, bumbling brunette capable of falling in love after one mediocre date. But Johnson is also secretly the superhero G-Girl, a blond bombshell who can fly, throw cars and burn through metal with her eyes.

Thurman, 36, talked about this super role and which superpower she’d like to have:

Why did this role appeal to you?

I love comedy and I’ve been wanting to do comedy forever. This character is just basically an uncensorable human being who just can’t control her responses and reactions and is pretty much just out of control. The idea that someone just doesn’t think before they speak and just blows a gasket at every turn was just immensely fun and interesting for me.

What’s the most difficult thing about playing a superhero?

I guess you worry that it’s silly and you’re going to look silly. I worried about that in Kill Bill too, like, “I look silly with this sword in my hand”. It couldn’t be further from my personality, of course. When you make a stretch, when you take a leap, there’s always that gasping kind of terror that you’re not going to land on something soft.

What G-Girl power would you really want to have?

The flying is pretty appealing. Of course the super sex.

It’s so funny in the movie that you have to say to yourself, “Well that would probably be a pretty good one”.

What does the “G” stand for in G-Girl?

Gorgeous. G-Spot. Great. Grand. Gregarious. Originally... She was X-Girl. And there was a problem... I personally sat down and went through the alphabet. And G for girl, G for gorgeous, the sexual connotation, every single thing about it seemed... very suitable.
