Popular mythology claims that Johnny Weissmuller did his own high-dive stunt in Tarzan's New York Adventure (1942). In the film, an escaping Tarzan jumps 200 feet (61 m) from the top of the Brooklyn Bridge, but according to ERBzine and research on Edgar Rice Burroughs, the shot was filmed by cameraman Jack Smith on top of the MGM scenic tower on lot 3, using a dummy plunging into a tank of water.
Tarzan's New York Adventure (1942) was the final time that Maureen O'Sullivan would reprise her role as the character "Jane" in the Johnny Weissmuller Tarzan Franchise, and her last motion picture until 1948. She wanted to devote more time to her seven children with her husband director John Farrow, including daughter Maria (AKA Mia Farrow).
Cheeta's famous laugh was supplied by former Our Gang member Mickey Daniels. The same recording found its way into dozens of films, usually for an animal, but sometimes for Mickey himself.
Cheeta's screen time per film had been increasing over the last couple of entries in the series. This one is considered her best performance, and clocks in with her most frequent and lengthy scenes.
The airplane, bearing the British registration of G-AECT, is the same plane that was destroyed in a crash in Tarzan Finds a Son! (1939). Unlike an airplane such as the Dakota, which has a cargo door, this plane has no such door, which means the lion cages wouldn't fit, and even if they did, there is simply no room on such a small plane for more than one cage.
