Taxi Driver inspiration for the bubbling pot scene

I thought that the camera moves in Taxi Driver that simulates Travis Bickle's fixation for his glass of headache tablet water could be good for when the Anna stares at the pot. The pot bubbling sounds could overpower the scene so, that it feels more intense when she is horrifyingly transfixed on what the contents of the pot could be.

The storyboard images are crude, but Martin Scorsese is brilliant at composing shots so the whole thing is worth a watch, but to just see the glass scene just watch from 0:53 to 1:20
