Harold occasionally mentions watching Traders, a show where Patrick McKenna played the role of Marty.
One of Edgar K.B. Montrose's first appearances had him talking about the film Dances with Wolves, talking about how the "Native guy" (the role played by actor Graham Greene), should have gotten the Oscar.
Wayne Robson played a down-and-out man in One Magic Christmas, who is so desperate for some money that he robs a bank — and accidentally commits murder! Not to mention hijacks a car with some kids in it!
Cast the Expert: Joel Harris (who played Young Walter) is a professional stuntman, making him all the more qualified to portray one of Possum Lake's resident butt monkeys.
Dawson Casting: An egregious example; McKenna was 31 when he started playing teen-aged Harold. Averted in the later episodes, in which Harold was portrayed as an adult.
Executive Meddling: Steve Smith isn't too fond of the second season, during which the executives pressed him to make the show into more of a sitcom. Hence the expanded cast and plotlines that we actually saw develop, as opposed to simply being related by Red. When Smith got back full creative control from the third season onwards, he went back to the old format.
Written By Cast Member: Taken to its literal conclusion. Steve Smith co-wrote all 300 episodes. Rick Green co-wrote every episode for the first eight seasons and the last two or three seasons. Later cast members like Peter Wildman and Bob Bainborough would also contribute to dozens of episodes in their own right.
