Noel and Michael watch the last Tarzan movie of the 1940s, in which Johnny Weissmuller has been replaced as the ape man by Lex Barker. They discuss Barker's alarming post-Tarzan behavior and how knowing that affects viewing his work, including Tarzan's Magic Fountain. And they also bid farewell to Brenda Joyce in her last appearance as Jane.
In the episode, a publicity photo is mentioned in which Sol Lesser took a picture of his new Tarzan with the original movie Tarzan, Elmo Lincoln, who had a tiny role in Magic Fountain. Here's the photo that Noel found.
