Robert Rodriguez, talking about how he came up with the woman with a machine gun leg idea:

I needed some sensational central image to help get across in a trailer and a poster. People have seen zombies. It needs some other hook. I’ve got the girl with no leg, then suddenly, I just pictured her firing a machine-gun leg. I thought, ‘Oh my God, that would be such a sexy, cool image, especially if it’s done really low-budget, where it’s not a “Terminator” fancy leg. It’s just a stump with an Ace bandage and a gun jammed in it.’

It is a powerful, memorable image. And for better or for worst it was the element most readily associated with Planet Terror, and perhaps with Grindhouse as a whole.

Considering the disappointing box office take of Grindhouse it just might have been for worst. But I still love it anyway.
