The National Theatre focuses its Summer Cinema 2010 on the films of Cary Grant, including the 1940 screwball romantic comedy His Girl Friday, by the legendary director Howard Hawks. Grant stars as a conniving newspaper editor trying to keep his ace reporter and ex-wife, played by Rosalind Russell, from quitting and getting re-married. The whipsnap banter between the two stars is truly movie magic from a golden age of cinema long past. Monday, July 19, at 6:30 p.m. National Theatre, 1321 Pennsylvania Ave. NW. Tickets are free, and distributed 30 minutes prior to screening. Call 202-628-6161 or visit nationaltheatre.org.
