Donaldson actually got to meet the real Burt Munro while making a documentary on the man in 1971 so a lot of what is in the film is based on first hand experiences with him. The director talks about how he got Anthony Hopkins interested in doing the film and how he got it financed independently with the help of his wife. Donaldson also points out what in the movie is based on fact and what was fictionalized for dramatic purposes. He is not only an expert on Burt but also a motorcycle aficionado, delivering an extremely informative track.
