The first time I saw this, I was amazed. It's even better when the music can be heard more clearly.
Of course, the 3 or so minutes after it are great too.
The rest of the film is hit or miss, but this scene in particular is incredible, made more impressive by the knowledge that Hanks improvised his part entirely.
Sadly I couldn't find a clip of it but the above moment from Hanna is my favorite from that film. The overly warm colors, her first truly emotional scene with someone other than her father, and on top of that it has some wonderfully impossible shot composition going on with both girls lying down on their sides, face to face but every shot has them both lying on their left arm so they take up the same space. It is so good.
