Before it leaves toward the end of July, "Italian Master Drawings from the British Collection," an exhibition of 61 works from the Renaissance to the rococo, from Leonardo to Raphael, is worth a second or a third visit. It's a best-of-the-best selection. CLASSICAL MUSIC

Starring Richard E. Grant and Paul McGann, "Withnail and I" is a cuttingly smart comedy about two youngish actors in London in 1969. This is filmmaker Bruce Robinson's directorial debut -- his screenplay for "The Killing Fields" was previously nominated for an Academy Award -- and it's a remarkably accomplished first outing for him. The performances, particularly those by the leads, Richard Grant as the brilliant, mercurial, cowardly Withnail, and Paul McGann, as "I," are shrewdly funny and filled with unresolved emotions. And as Withnail's piggy, rich Uncle Monty, Richard Griffiths, is terrific, too -- truly revolting and truly touching. POP MUSIC
