The 2011 film Sherlock Holmes: A Game of Shadows is based in part on "The Final Problem".  Like the story, it ends with Holmes and Moriarty plummeting into the falls, and Watson is shown writing the final sentences of "The Final Problem" on his typewriter. However, in the film, the characters are attending a European Peace Conference held near the falls which Moriarty seeks to sabotage, and the two plunge down from a balcony overlooking the falls rather than from the ledge of the original story. Holmes is also shown falling over the edge with Moriarty rather than simply being assumed to have fallen, being too injured to defeat Moriarty in a straight fight but knowing that Moriarty will go after Watson if he lives. While Holmes is shown to have survived, having used his brother's oxygen inhaler to survive the water at the bottom of the falls, Moriarty's fate is less certain.
