Two well known Washington Post personalities -- advice columnist Carolyn Hax and movie critic Ann Hornaday -- will talk about Robert DeNiro’s new flim, “Being Flynn” at the Landmark Bethesda Row Cinema March 14. This is the kickoff of Washington Post Live’s 2012 film screenings and discussions. Hax and Hornaday will take questions from the audience when the film credits start rolling. The film is about father-son relationships --”unbreakable and fragile” as the producers say. DeNiro plays one complicated dad in Boston with a son who writes about it. Since the movie is based on Nick Flynn’s 2004 memoir, I asked Flynn to join us at the screening. But he couldn’t get to Washington and had been on the road a lot lately so, perhaps mindful of all the time he spend away from his father, he said he wanted to spend time with his family.
