It's very rare that a woman is the front liner for thrillers like this. This has the potential to match up with thriller spy franchises (albeit this isn't a spy movie - but the momentum it gives is similar). With Johansson's exposure in action franchises, as well as her acting ability, it's no doubt that she seems to be a perfect choice for the title character. The trailer shows that the film has promise, and this is one that I'm definitely excited to see. I've like Johansson's work by far, and I don't think she will disappoint in this one.
