Because Guy aged rapidly, living out an entire lifespan during the course of 3 days portrayed in a single episode, multiple actors were used to portray him at different ages. The actors who portrayed Guy were: Riley Smith, Michael Welch, Bobby Edner, Matthew Josten, Richard Stobie, and Victor Bevine.
