The doll is an authorized likeness of actress Megan Fox, Saloon Leila. She's 16" tall and is a limited edition of only 200 dolls. She is priced at $149.99.
I haven't heard of this movie yet, but the doll is quite interesting, I have to admit. (I'm really starting to wish I bought tickets. Paulette Goodreau will be at Comic Con this year, too.)
