An entertaining, adroitly cast adaptation of Oscar Wilde’s 1895 play by writer-director Oliver Parker, though the expansion of settings and reduction of theme that one might expect from the Miramax label is at times distracting. Trivialized Wilde could sound like an oxymoron, insofar as he functioned rather like Neil Simon in the London theater of a century ago, but this play has its serious as well as its flip side, and the flipness gets much more of Parker’s attention. Though this isn’t a musical, it often feels rather like Gigi (Charlie Mole’s music is particularly effective). With Cate Blanchett, Minnie Driver, Rupert Everett, Julianne Moore, Jeremy Northam, John Wood, Lindsay Duncan, Peter Vaughan, and Jeroen Krabbe. (JR)
