A two-hour program of shorts selected and hosted by Gregory Lukow, chief of the Library of Congress’s Motion Picture, Broadcasting, and Recorded Sound Division. On the basis of two classics in the program that I’ve seenGjon Mili’s great jazz documentary Jammin’ the Blues (1944, 10 min.), with a priceless appearance by Lester Young, and Chuck Jones’s 1957 Bugs Bunny cartoon What’s Opera, Doc?this should be well worth checking out. Also screening are The House I Live In (1945), a piece of liberal propaganda on behalf of racial and ethnic tolerance starring Frank Sinatra, and The Happy Hottentots (1930), a one-reel comedy. (JR)
