Wilhelm was born into a film family. His father was silent film child actor and second unit man Otto Wilhelm Von Hohenzollern whom was called Willie Hon because it was easier to say it then his name.

His grandmother Mary L Shriver came west in the early days of the industry and became a script supervisor and not a actress like she wanted because she was a stickler for making certain things being done right and not a very good actress. The only time she ever acted was in the 10 Commandments.

Both were responsible for him becoming what he became and getting lots of float in float out work over the years proving nepotism does work. To many he was simply known as JR or Willie's kid or Mary's grand kid.

Shortly after he was born in 1932 he was used as a stand-in in a stunt that required a child be thrown from a wagon in a land rush western. Thus a career that has lasted in the industry for over 80 years was born. He is highly recognizable because of his blond hair and big ears. People are always coming up to him asking to take pictures with him
