Director W.S. Van Dyke had a reputation for getting things right the first time. Two movies he directed in the 1920s were shot on location in Tahiti. For Trader Horn (1931), he spent seven months filming in East Africa. His best known movies, however, are The Thin Man (he also directed three of the sequels), Tarzan the Ape Man (filmed in Hollywood, it used stock footage from Trader Horn), and several Jeanette MacDonald and Nelson Eddy films. ClassicMovieHub.com has several behind-the-scenes photos of Van Dyke at work.
