there were no digital effects used in that shot. they actually had David Bowie hanging upsidedown on this rig system with his boot glued to the brick. then they just flipped him around and were like, ok David, don’t die.
So basically, Jennifer Connelly didn’t even actually have to work for that expression, she’s just going “OMG HE ACTUALLY DIDN’T BREAK HIS NECK!”
actually there was nothing whatsoever used in this scene, that’s just how bowie walks
David Bowie out of fucking nowhere
