The story was adapted in 1980 as an episode of the Soviet TV series "The Adventures of Sherlock Holmes and Dr. Watson" starring Vasily Livanov. The episode has some minor departures: Moran tries to shoot Holmes during his fight with Moriarty (he actually appears in the story before Moriarty, and both Holmes and Watson are aware of his motive to kill Adair from early on), with Holmes pretending to be hit to fake his death, Adair is still alive at the start of the episode, Watson unsuccessfully tries to protect him as instructed by Holmes, and Watson briefly becomes a prime suspect in Adair's murder.
