Elizabeth Banks

Normally I wouldn't think I would confuse the two, but I don't recall ever seeing Banks as a brunette. Maybe in W.? Weren't they both in some Ryan Reynolds political rom-com? I would think that would cement their differences.
I suppose Ms Posey makes a good bridge between the two, although I'd have to find a photo of her to remind me exactly what she looks like. Mostly I know her from Dazed and Confused, but that was a small-ish part and I'm sure she looks a lot different in more featured roles and adult parts.
