Tarzan And His Mate | 1934
The sole directing credit of MGM's veteran Art Director Cedric Gibbons (The Wizard Of Oz, Meet Me In St Louis, Bad Day At Black Rock and many more) sees Tarzan (Johnny Weissmuller) and Jane (Maureen O'Sullivan) threatened by ivory poachers.
No expensive location jaunts here – the 'African' jungle is Sherwood Forest and Sherwood Lake, about fifteen miles west of Los Angeles. It's south of Westlake Village on Potrero Road just off Highway 101 near the Santa Monica Mountains. The name is no coincidence, it comes from the use as a location in the 1922 Douglas Fairbanks film of Robin Hood, and crops up again in 1938's The Adventures Of Robin Hood, with Errol Flynn.
The swamps were in Pico-Rivera, southeast of LA. More of the California locations include Big Tujunga and China Flats, north of Ridgecrest in the Mojave Desert – now a restricted Naval Weapons Center.
