One of his first gigs was a guest spot on Chuck Connors' The Rifleman. He then caught the eye of producer Aaron Spelling who was producing his very first series (of many, many to come), a western called Johnny Ringo. Spelling wanted a young deputy to play opposite the series' star, singer/actor Don Durant, and settled on the novice actor.
Goddard was with the show from 1960 to 1962, the third and final season being an hour-long program instead of thirty minutes. Adam West joined the show during that season as well. Goddard next filmed a semi-musical, Desilu-produced TV pilot with Ethel Merman called Maggie Brown, about a single mother who operates a South Pacific-set nightclub frequented by sailors (sign me up!), but it didn't come to fruition.
here in a profile I did on it a while back.
Now we know that this below is absolutely nothing more than a suggestive fold in the trouser leg of Mr. Goddard's and not a representation of Mark Jr., but isn't it fun to momentarily presume otherwise? (Click to, er, enlarge! LOL)
A final (to date anyway!) role came in 2010 with the obscure, low-budget movie Soupernatural. The story concerned the appearance of Jesus Christ serving soup at a church festival and the hubbub that occurs thereafter. Goddard was stunt cast along with a plethora of other “past their sell by date” stars such as Lou Ferrigno, Pamela Sue Martin, Dee Wallace, Butch Patrick, Paul Peterson and Kathy Garver (the last three former TV child stars.)
