Fans of that show still remember him today, but the rest of the world may not as the majority of his career was spent either as a guest star on other television shows, or a major player in minor films. This is a real shame, for Peter Breck had the talent and the looks to be a major star.
If one should happen to catch his other television credits, it will most likely be followed by a browse through IMDB only to discover the true meaning of the words "working actor". From Have Gun Will Travel to Perry Mason and Mission Impossible to The Fall Guy, Peter Breck time after time delivered quality work, but it wasn't always just in television.
His film work was not as prolific as his television resume, but the quality of his movie performances are as good if not better. Check out Sam Fuller's low budget independent film, Shock Corridor and see for yourself why Peter Breck is Not Very Famous...but should be.
