George Romero, the director who is singlehandedly responsible for the entire zombie movie genre, directed Knightriders in 1979 and cast Brother Blue for a significant role. Knightriders is a story about a troupe of renaissance actors who live out the days of King Arthur while riding a lot of motorcycles. Ed Harris is the character leading the traveling circus of jousting bikers. Brother Blue starred as Merlin, the magician, who travels with the merry band of re-enactors on his school bus. Take a good look at the trailer for several good shots of a 1979-aged Brother Blue.
