The short walk up Mass Ave to the Orson Welles Complex (something many young starlets once had) is well worth it this weekend. On Sunday, Cinema 2 starts showing two of French director Claude Lelouch's films, one of which--And Now My Love--is a romantic gem. Lelouch, also responsible for A Man and A Woman, is bold enough to film a love affair and yet leave his main characters separated until the last frames. As he develops the lives of his two lovers, Lelouch also traces the history of France in the twentieth century. While his character's political statements never rise above the level of glib Reaganisms, the film still manages to retain its charm. Also playing is another Lelouch feature, Happy New Year, a comic cops and robbers number.

A little farther up the street, Give 'Em Hell, Harry occupies Central II, and next door in Central I, The World's Longest Running Feature continues. (And I thought it a disaster when the Sound of Music lasted 2 years in my home town.) James Whitmore recreates his state role as F.D.R.'s heir in Give 'Em Hell, Harry and from all accounts does Mr. Truman justice.

One last note: Frederick Leboyer will present his film Birth, on natural childbirth, at 2 Divinity Avenue this afternoon at 4 p.m., not at the Yenching Institute.
