That look of drunkenness by the actor (Charles Rogers) who is poured the glass of champagne at the end of the shot - that's not acting, he's really drunk:
In the scene in which Rogers becomes drunk, the intoxication displayed on screen was genuine, as although 22 years of age, he had never tasted liquor before, and quickly became inebriated from drinking champagne.
Such detail to his craft, this is taking method acting to its absolute limits.
Imagine th trail of destruction behind the cameraman with his camera pushing through all the tables.
