I watched it a few times to see if there was any weird CGI shit or anything.

When he’s walking from Marine one to Air Force One he’s having problems walking. Whether it’s staged or not I do not know, but yes it looks like he’s having a problem with his ankle or knee or something. Always try to make it like he’s so fit, and how he does a short Jott to the stage or somewhere. He’s not, or whoever the actor is Doing a great job

Guarantee he just misjudged a step due to the mask. It's weird how they do interfere with sight in looking down. I've dropped my wallet and things multiple times at like a grocery check out. He refuses to take it off. Probably showers in a mask. I mean the man's walking on an open windy fuckin tarmac and he still thinks a mask is necessary? God save us from this moron.

I’m doing it. Over and over. Right foot failed. After that it’s hard to see what happened. Missed the step again? Leg just giving out? Why doesn’t he slow down? He picked up speed again on the top stairs. I’m studying it.

People have commented it’s a double. I see a very frail old man with possibly Parkinson's when I’ve seen him walk. When he approaches the plane, the wind is blowing his pants and you can see basically stick-like legs with no muscle tone. Surely, if they wanted a double, they’d get a tallish, thin guy but why so frail? His gait is definitely off. He marches sort of and his steps are short and fast. Parkinson’s. With Parkinson’s, as it advances, the steps even increase in speed as the body gains momentum, the core lacks strength and it’s difficult to remain upright. He seems to be nearing that sort of decline. It would be sad if he wasn’t such a POS.

Do you have any formal training to help you analyze it? Or just yolo'ing it
