Mystery Liner (MOD) (DVD Movie)

Captain Holling (Noah Beery) is relieved of his command after he suffers a nervous breakdown. When Downey takes over for the impending voyage, he learns that the ship will be automatically piloted by a radio-controlled mechanism created by Professor Grimson. A band of criminals is able to intercept the radio signals during a test of the device and dispatches saboteurs for the liner's remote-controlled voyage. Both Downey and the Professor are murdered and after the vessel shifts into automatic pilot the gangsters seize control with their own transmitter. Not a soul on the ship is above suspicion.

Mystery Liner features an interesting cast of character actors including Edwin Maxwell (the maniac killer in Columbia's Night of Terror), Zeffie Tilbury (Werewolf of London, Mark of the Vampire), Gustav Von Seyffertitz (The Moonstone, Son of Frankenstein), and a clean-shaven George "Gabby" Hayes. Much of the electronic lab equipment seen in Mystery Liner can be recognized as the same gear that brought the monster to life in Universal's Frankenstein series.
