This burnished adaptation of Ann Patchett’s 2001 novel is stylish but altogether unremarkable. Julianne Moore stars as a world-renowned opera singer (though her singing is dubbed by legendary soprano and Lyric Opera creative consultant Renée Fleming) who’s brought to an unspecified South American country to perform at a party for a Japanese businessman (Ken Watanabe). Things go awry when a group of revolutionaries storms in and takes everyone hostage; over several weeks, the partygoers and the revolutionaries become increasingly intertwined, and a few romances even develop among them. This is emotionally affecting at times, but writer-director Paul Weitz (American Pie, About a Boy) adopts a prosaic approach that abandons the source novel’s lyrical persuasions—it feels much like his entertaining but ultimately uncinematic Amazon series Mozart in the Jungle. Still, Moore and Watanabe are winning in their respective roles, and the strong supporting cast is enchanting.
