Yeah, I think shows like this and the Twilight Zone really benefit from being shot in black & white. I believe it adds to their charm and better hides production shortcomings like cheap sets, garish stage make-up, or use of stock footage.
Also, there's something about B&W film that triggers your imagination in a way that color footage doesn't. Maybe it's just that your mind fills in the details like the color of a room's walls or how dingy a character's outfit may appear to other characters.
I agree. The film noir-ish aspect works much better in b&w. I will also take a half-hour grayscale Gunsmoke any day. The color ones were still great, but they seem to lose a storytelling... directness? I can't put my finger on it. Wagon Train and Laramie were also better in b&w.
Gunsmoke and Maverick also had great mail order bride stories. One on Maverick was in a later season and was also a funny parody of Bonanza. But I have also noticed the similarity of the GR HGWT story and "Mudd's Women."
In his great memoir, frequent HGWT guest star Harry Carey Jr. said that Richard Boone was very outgoing and a natural leader in all areas. He made it sound like Boone was the main motivator behind the extensive location shooting because he liked to "get out of town," especially to Lone Pine, California, where they had a "home away from home" hotel and Boone could lead extended nightly partying. He would try to get Andrew McLaglen to over-indulge, Carey said, but McLaglen would defeat him by falling asleep and no one could wake him up.
Carey said that James Arness was also very influential and respected behind the scenes on Gunsmoke, but was a more reserved and businesslike type of guy. He makes it sound like great fun working on Westerns in those days, where everybody knew each other (his father in law was Paul Fix). He was used to a "family" of cast and crew from working on John Ford pictures, and made HGWT sound similar. He says the standard rate for guest work across all the shows was $750 for six days.
