Mister Dynamite is a 1935 American action film directed by Alan Crosland and written by Doris Malloy and Harry Clork.

The film stars Edmund Lowe, Jean Dixon, Victor Varconi, Esther Ralston, Verna Hillie and Minor Watson.

Thompson, nicknamed "Dynamite" due to his initials, takes an interest when a man is murdered in San Francisco leaving a casino.

The dead man, D.H. Matthews, had an argument outside the casino with Jarl Dvorjak, a celebrated pianist who was gambling while his aloof and money-mad wife Charmian was away.

When the pianist himself is shot while playing an organ, Thompson puts everything together and reveals to all that Matthews had actually been a son of Dvorjak's from a previous marriage who was conspiring with Charmian to gain his fortune.
