In Stanley Kubrick's film The Killing, several men are assigned roles to ensure the successful heist of a racetrack. As the heist unfolds we see Marvin appear in the track lobby visibly drunk. (Marvin was the character who previously bet $5 on all the horses to win in the first racetrack scene) His drunkenness concerns both the bartender and Sterling Hayden's character.
What was he supposed to do? I get a sense it may have been something to do with the public-facing door used to gain entrance to the cash room, but I'm not sure what he could have done.
Did I miss something?
