Ew, Zooey Deschanel.
Carano's not a great actress, but she does have the whole "super-toned" thing going for her, and she can definitely do her own stunts and fighting. Gado trained in the Israeli military (it's required over there) before trying her hand in acting, so I assume she's got at least some experience with the physicality that the role will - more than likely - require. I think Carano's got a lot more screen presence. Neither one of the ladies has really impressed me much as an actress...kind of why I was hoping for Hayley Atwell (or Jamie Alexander).
I really hope she bulks up for the part. She's easily the tiniest cast member in Fast Five and Six. I know that's comparing her to guys like Dwayne and Vin Diesel, but still...she even looks itty-bitty when they sit her next to Han (the Asian guy) and that's when she's wearing thigh-high boots.
Maybe they can do the Gandalf camera tricks to make her look bigger? Or we should just get used to Wonder Woman staring Superman in the chin.
