The trailer for Rebecca Miller’s The Private Lives of Pippa Lee — starring Robin Wright Penn as a formerly content housewife having some doubts about her life — is here. Penn’s getting Oscar buzz for her subtle performance, though she doesn’t do much heavy lifting in the mostly lighthearted scenes shown here: The trailer jumps from Blake Lively as young Pippa dealing with her pill-popping mother (Maria Bello), to quiet dinners with her older husband (Alan Arkin), to surely life-enervating flirtations with Keanu Reeves. Julianne Moore and Winona Ryder also appear in different stages of Pippa’s life. This looks pleasantly agreeable.
