“Salt” premiers with high expectations partly (or probably, mainly) due to Angelina Jolie. I love spy-thriller movies but couldn’t recall seeing one with a female lead. Jolie is, without a doubt, the obvious choice for the role. There are very few female stars who could open a blockbuster action movie. Milla Jovovich is one, Kate Beckinsale is another, but they’re more fantasy-based. It would be unfair to compare “Salt” to “Wanted,” as that, is fantasy-based too (bullet-bending, anyone?), as with “James Bond.”
