Quick: Do you know who sat in Rush Limbaugh's radio-host chair before the big dittohead? Three local filmmakers—Seth Kramer of Red Hook, New York; Daniel A. Miller of Cold Spring, New York; and Jeremy Newberger of Yorktown Heights, all from the Garrison, New York-based Ironbound Films—certainly do. The three were fans of the controversial Morton Downey, Jr. long before they knew each other. Recently, they made a documentary about the firebrand talk show host. Évocateur: The Morton Downey Jr. Movie will have its premiere on April 19 at the Tribeca Film Festival, which will also host three other screenings of the movie.
