I will have to see it now just for that reason.

It's funny how the mind works. I thought of DiCaprio as well, then eventually realized it was probably mostly because of the opening scenes of Inception. Similar angles, lighting, atmosphere, and so on.
I was also thinking of Michael 'the guy you hire when you can't afford DiCaprio' Pitt, specifically his role in the Dreamers.
Definitely agree with the Jodie Foster comparisons as well.
By the way, I just discovered Mozilla actually recognizes 'DiCaprio' as a word!
Never defend crap with 'It's just a movie'

Haha, same here. I kept thinking I knew her face from somewhere but couldn't place it. I didn't want to look on here until after I watched it because I didn't want to get spoiled for any twistsprolly a good idea too. But anyway, after looking at her page I see nothing that I know her from. I wondered once or twice about the Leo thing, but I know his face pretty well, his build etc,so I knew it wasn't him. Still, the resemblance is uncanny.I guess that explains the recognition.

Agree, also kinda reminded me of Jodie Foster in Predestination, the way she talked, mannerisms.
