Lookout Daniel Radcliffe

I've yet to see a film featuring Sienna Millar, so I'm not qualified to comment on her acting talents. But I can put 2 & 2 together & divine that Ms Miller has top class talents in other areas.

Consider - if you happen to be a young, presentable actor, and especially if you're British, it's probably only a matter of time before Sienna will get around to you.

SO look out Daniel! (Or perhaps more likely, Rupert Grint.)
