Art house comedy hits all the right notes

The plot of The Piano in a Factory is easily summarized: A father makes a piano of steel to win over his daughter from his wife.

The film is amusing and warm, dealing with parental love and friendship, but it was neither easy nor amusing to make.

China's film market, although boasting an annual box office growth of 35 percent since 2003, leaves little room for art films, between domestic extravaganzas and Hollywood blockbusters.
