When Hannegan and his friend go into the saloon, they enter from the street. When they are briefly seen from inside the saloon, standing by the doors, a wall is seen right outside. There should be a street scene or a view of buildings across the street. This is more noticeable when Wyatt stands outside, watching what's going on. The wall is fairly close to him and the camera holds on him for several seconds.
When Wyatt leaves the saloon, Edith is waiting for him. She says that she is done for the night and she asks him to walk her home. It seems to be a little dark out, except for possibly some streetlight effects to show Edits and Wyatt. As they are walking, Doc Holliday shows up and it is now daylight, with a lot of people walking around as they would during the day.. A few minutes later, it is dark again. This is a frequent issue though out the series.
When hit by Wyatt, Hannegan falls back and slides down the wall to the floor. He still has his hat on. The camera changes back to Wyatt, then Hannegan again, and his hat if gone.
During the brawl at Haley's Pool Hall, the stunt men stand-ins for Hugh O'Brian and Leo Gordon's character Hannegan are very noticeable if you focus on their faces during the fight.
During the episode, Edith identifies herself as Edith Peterson, but the character's name is listed in the closing credits as Edith Rickabaugh.
