I am no comic book fan. But I love them depicted on the big screen. :)
With that, here are my top five favorite comic book-turned-movie oozing with girl power (honestly, I dislike that term but I just cannot find the right word for it).
played by Jessica Biel in Blade 3
played by Halle Berry in Catwoman
played by Jessica Alba in Fantastic Four
played by Jennifer Garner in Elektra
And my most favorite:
played by Angelina Jolie in Tomb Raider
I heard Black Widow played by Scarlett Johansson in Iron Man 2 had something to say for herself, too. I still have to watch it, though.
