When Matt is in the bank speaking with Drew Holt, the scene cuts to Gen. Parsley Smith yelling on the sidewalk. Matt can be seen in the background walking towards the action, yet the next cut is back to Matt still in the bank with Holt.
In the opening scene in the series first season where Matt is walking through Boot Hill you can see one of the headstones swaying in the wind indicating these are either made of cardboard or foam.
