Hard to believe this hasn’t happened already: Greg Kinnear is set to direct a feature film. The Oscar-nominated actor will also star in “Phil: A Tale of Flossing and Plumbing” (working title) that Showbiz411.com also reports will star Emily Mortimer.

The storyline focuses on Kinnear’s Phil character, a dentist who suddenly is faced with a patient dying in his dental chair. Phil then decides to pretend he’s a Greek plumber — which will make it possible for him to get into the house of the man who died.

In the course of getting close with the family, he falls in love with the late patient’s widow, played by Mortimer. The screenplay is being penned by Stephen Mazur, who wrote Jim Carrey’s 1997 hit movie, “Liar Liar.”
