Filipino director Joven Tan made the provocative Naked Nights (2001) after a year of studying the lives of strippers and sex workers. “This is probably the most passionate movie I have ever made,” said Tan, who is not known for onscreen modesty. Beginning with footage of a live sex show, Tan’s drama continues with plenty of fireworks. Most of them are provided by principal actress Aya Medel, who inhabits her role with breathtaking realism, including a series of tantalizing turns in the buff.
