In the upcoming Wolverine movie
If you don't know who Silver Fox is, in the comic books she's a girlfriend of Wolverine's and one of the few female members of the Weapon X project, which gave Wolverine his adamantium skeleton. Without wanting to spoil anything, her path is not a particularly happy one.
Q would be a terrific choice for a role like this, disregarding the fact that Silver Fox is a native American in the comics because, well, what the hell difference does it make what race she is? She looks great, of course, but she's also not unskilled in the art of arse-kickery. She could kick your sorry butt all over the shop. Oh yes she could.
