It's not surprising that director Joel Hershman is American. "Greenfingers" is straight out of the Hollywood feel-good school of filmmaking, with simple homilies, an upbeat finale and positive values about making something of oneself. It certainly has none of the complexity of "Croupier," Owen's last film. "Greenfingers" may be based on a true story but it feels inauthentic. Starring Clive Owen, David Kelly and Helen Mirren. Directed and written by Joel Hershman. Produced by Travis Swords, Daniel J. Victor and Trudie Styler. No distributor set. Drama. Not yet rated. Running time: 91 min.
