Here are a few people that I think look like Marisa. I've included pix of them so you can see for yourself, they might not the best examples but I promise if you watch these women elsewhere it'll be obvious. Any to add? LMK!
Mila Kunis of That '70s Show
Sarah Brightman
(opera singer)
Salma Hayek was kidnapped by Marisa in the WWW video ;)
Rose McGowan of Charmed
Jessica Alba of Dark Angel
Christina Ricci even sounds like Marisa!
