Please note that the algorithm for providing 'Known For' listings on an actor's page seems to be lacking in details. For example, the page on Gene Kelly shows him to be 'Known For' Leon: The Professional, even though he is listed in the Soundtrack category of the movie for some mundane reason. The 'Known For' category should highlight the movies where the performer has played an important role. I have noticed this error in pages of some other actors too. Hope that the Imdb team looks into this matter and uses a different approach to make this section more meaningful.
