Fun fact I learned from talking to Aaron Conners at the Fan Fair: Chris Jones, who plays Tex Murphy, doesn't drink or smoke. Like, AT ALL. He had to be coerced into lighting a cigarette in Under A Killing Moon, and you never see him take a full drag off one.

Also, if you look closely in the opening cinematic in Under A Killing Moon, when he pours himself a glass of bourbon, the cap is still on the bottle.
