Mandy Bombard analyzes body-language on YouTube. One of her videos is about Adolf Hitler. She concludes from observing Hitler that he is not the cold and vicious figure portrayed by Hollywood.
"It told me, as I watched this, that he really did have a fondness for the German people."
"He was not as standoffish as he was made out to be."
No surprise there, really. Anybody who tries to look at Hitler objectively will get a much more positive impression than what propaganda has portrayed.
She goes a bit off the rails near the end, speculating about matters that have nothing to do with body-language. (1) Hitler's hand-tremor was not caused by drugs. He was diagnosed with cardiac sclerosis in 1941 and aged rapidly after that. He may have had Parkinson's disease, or he may have had a condition called benign essential tremor. (2) It is extremely unlikely that Hitler went to Argentina, because he was very sickly with a short life-expectancy in 1945 and none of the witnesses ever deviated from affirming that he died in the bunker.
