Last Days Of Pompeii, The (1935) - In Caesar's Name!

SPOILER except the title suggests Vesuvius will erupt, more special effects are deployed as Marcus (Preston Foster) chooses his wounded Christian son (John Wood) over his Roman prefect master (Louis Calhern) and his troops, in the disaster epic from RKO’s King Kong team (Merian C. Cooper, Ernest B. Schoedsack), The Last Days Of Pompeii, 1935.
