Help with hi-res pic, plz plz????

Dear listsibs and freinds

I have found what I want to be my icon but I don't know how to make screencaps from a DVD (my Mac won't allow it) and this pic is from a crappy youtube still and is crap. I would love a high resolution version of just this, and does anyone know how to get this???

It is from the final minutes of Inception when they all wake up in the plane (and Cobb exchanges looks of love with Saito).

Thank you, my darlings, in advance for techie wondrousness!
