Michael popping pills on the train in !!... the first sign that the stress is getting to him and that his body is starting to break down.
Or his nerve. I bet the pills were Miltown, the universal tranquilizer of the Fifties.
Another little moment: During the New Year's Eve party at the Capri in Havana, Geary gets a lascivious grin on his puss and says, "I'll try one of those red-headed Yolandas." If you run the DVD on slo-mo, you can see Michael rolling his eyes as if to say, "There he goes again--thinking with his dick. Didn't he learn anything from that brothel murder?"
Michael has a similar expression in the Moe Green meeting when Moe says the chef will cook for him special and the dancers will kick his teeth in.
"Io sono stanco, sono imbigliato, and I wan't everyone here to know, there ain't gonna be no trouble from me..Don Corleone..Cicc' a port!"
