Something I love about the Hank/Walt garage scene
So for most of the show, when these 2 would interact Hank is portrayed as the more "dominant" person. He's shorter yea, but has a bigger/strong physical presence. He's loud, can be obnoxious, and just kinda trying to dominate the conversation. Even when he was laid out after being shot, they don't deviate too much from this dynamic.
The garage is the first time Hank meets Heisenberg, and I didn't really pay attention to the terrific way it's shot until this recent rewatch. There's a lot of angles where you see Hank but it's over Walt's shoulder, and kinda shot downwards so they really emphasize the height difference between the two. The dynamic has been totally flipped, it's Walt/Heisenberg that looks to be the more dominant one, even physically. And he's controlling the convo.
Even when Hank roughs him up a bit, Walt stays in control and that's when you see that look of confusion/fear in Hank's face.
