Mark of the Vampire (also known as Vampires of Prague) is a 1935 horror film, starring Lionel Barrymore, Elizabeth Allan, Bela Lugosi, Lionel Atwill, and Jean Hersholt and directed by Tod Browning. It is a talkie remake of Browning's 1927 silent London After Midnight with the characters' names and some circumstances changed.
Mark of the Vampire was originally 75 minutes, but was cut back to 60 minutes by MGM. Reportedly this was due to incestuous overtones - then unacceptable by the standards of the Production Code - between Count Mora (played by Lugosi) and his daughter. However, the audio commentary on the DVD makes no mention of incest but suggests that much of what was cut was comic material, particularly surrounding the maid.
