I believe this is the RKO Ranch in Encino, as it appears in the 1954 Dragnet episode “The Big Producer.” It’s a good one, one of the best in my opinion, about a washed-up silent movie producer reduced to peddling pornography. There’s a strong Sunset Boulevard (1950) vibe to it, with Jack Webb and Ben Alexander joined by Ralph Moody, Martin Milner and Carolyn Jones.
This seems like a good way to plug The Jack Webb Blogathon happening over at my other place, The Hannibal 8. It’s running through the weekend (beginning on Friday, naturally), and some great folks are contributing (including our friend Laura and my daughter Presley). Stop by if you get a chance.
