McBeath as the obsessed Quint in True Heart
McBeath's film history is quite extensive (especially considering he is primarily a stage actor).  He has portrayed a wide variety of characters, ranging from a poacher to a priest.  Listed below are his theatrical and television film credits.  Click on an underlined title for more information about that particular movie (pictures, character information, film and/or character commentary).

Films currently without links will hopefully be added in due time.  McBeath has also appeared in at least two short films, "The Alley" (18 minutes) and "The Fisherman and His Wife" (11 minutes), which may not be obtainable for the purpose of making vid caps.  Sorry, kids.
