Luke Conner told me that he prefers solid color animals for movie work, since they can easily be 're-used' in multiple shots. I told him that I always joke with my high school students that his oxen were traitors: They clearly fought on both sides in the American Revolution- sometimes pulling British Wagons, others Continental farm equipment in the show Turn: Washington's Spies. Using black Swiss-Holstein crosses made it an unlikely catch by most viewers used to bad TV**.
This fact stood out as I watched some of M*A*S*H*, Season 5 on Hulu. Within the first few episodes, the same ox was working both as a single and in a span. With multiple owners. The traitor.
At least M*A*S*H* now qualifies as good TV. What else do you watch that qualifies as Good TV?
** Bad TV: TV without Oxen featured regularly
