Funny he mentioned Parker Posey, because I had to stop myself from mentioning her when I wrote my response. Damn right.

Thanks for the full context of the quote -- this is exactly why I admire directors who cast Toni Collette. She consistently displays a range that most actors cannot hope to match. From Muriel to Carla (and everything in between), she never fails to amaze me.

As for Ewan, I suppose this fitness for the part is so obvious in retrospect that it's hard to imagine Todd not immediately leaping to that conclusion. Extrovert, yes. Repeatedly and proudly naked in almost every film? Yes.
