Identifying the features of a genre: The Three Musketeers

The Three Musketeers is an action adventure of the swashbuckler sub-genre. We can tell this because there are dramatic, long-drawn-out scenes of sword-fighting which are often emphasised by slow motion closeups. The costumes & scenery are lavish, over the top & accordant with the time period the film is set in.
 The music is sweeping & epic to demonstrate the importance of the events in the film. There are many points in the film when royalty & the royal palace are involved; the regal music matches the regal setting for these segments.
