"Roxanne," a 1987 film written by, and starring, the comic genius Steve Martin is yet another film from the fertile 1980's that more people should be happy to know.  It's based on the 100-year old French play "Cyrano de Bergerac," by Edmond Rostand. And it costars the long-legged blonde Daryl Hannah, makes good use of Shelley Duvall, Fred Willard, and Michael J. Pollard in supporting roles, was directed by the talented Australian Fred Schepisi. It's set, supposedly, in a pretty Oregon skiing town; actually filmed in a pretty Canadian town; the cinematography presents us with many green and charming vistas.
