If you missed "An Inconvenient Truth," the Oscar-winning documentary about global warming, you can see it on the big screen as part of a "Cautionary Tales" Sunday series at the Regent Square Theater.

Subtitled "To Do No Harm," the four-movie lineup is being presented in May by the Pittsburgh Chapter of Physicians for Social Responsibility, KQV, City Paper and Pittsburgh Filmmakers. Guest speakers will follow each film at the theater, 1035 S. Braddock Ave., Edgewood.

The event kicks off May 6 with the Davis Guggenheim documentary about global warming that turned Al Gore into a red-carpet regular and an Oscar winner. In his elaborate, engaging science lecture, he looks at why the warmest years on record have come since 1990 and why glaciers are melting, seas rising, and storms, floods, droughts and wildfires increasing in ferocity.

On May 13, the selection will be another Oscar winner, "Fog of War." Documentary-maker Errol Morris allows Robert McNamara to take viewers on an insider's journey through some of the seminal events of the 20th century, from the firebombing of Japanese civilians in Tokyo to the Cuban missile crisis and the Vietnam War.

"Manufactured Landscapes," a winner at the Toronto Film Festival, will be the May 20 feature. Jennifer Baichwal's documentary offers a portrait of Canadian photographer Edward Burtynsky, internationally acclaimed for his large-scale photographs of nature transformed by industry.

The series will close May 27 with the satire that placed third on the American Film Institute's list of the 100 funniest American films. "Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb" was right behind "Some Like It Hot" and "Tootsie." Peter Sellers juggles three roles in the satire of the American war machine.

Admission is $7 or, if you buy a four-film pass, $18. Start time is 7:30 p.m.
