The Dragon Murder Case is a 1934 mystery film adaptation of the novel of the same name by S. S. Van Dine, starring Warren William as private detective Philo Vance, Margaret Lindsay, Lyle Talbot and Eugene Pallette, and featuring Helen Lowell, Robert McWade, Robert Barrat, Dorothy Tree, George E. Stone and Etienne Girardot.

Monty Montague disappears after diving into a natural pool of water on an estate.

Philo Vance and the District Attorney come to investigate and decide to drain the pool.

It was offered to Michael Curtiz, Archie Mayo, Mervyn Le Roy and Alfred Green, all of whom turned it down.

[1] In his review in The New York Times, Mordaunt Hall found that the "denouement is scarcely satisfactory, for it is not quite clear how Mr. Vance reaches his conclusions."
