So long as the rain stays at bay, Bainbridge’s Downtown Association will be cranking the digital reel to reel in waterfront park on the Island this month.

This Saturday marks the next installment of and the beginning to this year’s free Movies in the Park series — an annual island fixture. What would’ve been the first installment — July 20, inline with the latest Harry Potter book release — was rained out.

So with fingers crossed for hot August nights, movie-in-the -park-goers are encouraged to bring their own lawn chairs, picnic blankets, family and friends for a few evenings of classic cinema.

And for those extra enthusiastic movie lovers, costume and trivia contests catered around that night’s feature will precede show time.

Movies start at dusk, refreshments will be available, with a popcorn machine provided by event sponsor CFA Northwest Mortgage Professionals, said Ashley Armstrong, an event organizer with the downtown association.

“It’s really for everyone,” Armstrong said. “We just want to put on a great event, for free, that everyone can enjoy.”

So here it is, the list and small summaries new and old classics slated for 2007 Movies in the Park:

(All movies start at dusk in waterfront park, preceded by costume and trivia contests centered around that evening’s feature.)

• Aug. 4 — “Back to the Future” directed by Robert Zemeckis, produced by Steven Spielberg (1985)

A teenaged Michael J. Fox stars as Marty McFly — a rogue high schooler and friend of mad scientist Dr. Emmett L. Brown (Christopher Lloyd) — who is transported back to the 1950s and thrown into the midst of his parents’ teenage courtship, after fleeing from 1985 terrorists in a time machine which Brown had fashioned out of a DeLorean. Will he alter the course of history, will he make it back to the future?

• Aug. 11 — “The Philadelphia Story” directed by George Cukor, produced by Joseph Mankiewicz (1940)

An “upper crust” comedy said to be a “brilliant adaptation” of Phillip Barry’s play set in the high society of Philadelphia “Mainline.” Tracy Lord (Katharine Hepburn) is a wealthy heiress in search of romance, Cary Grant plays her ex-husband and James Stewart plays a reporter who falls in love with her. There’s not much better for the dog days of summer than a good old-fashioned love triangle.

• Aug. 18 — “E.T.” directed and co-produced by Steven Spielberg (1982)

One of the ultimate underage fantasy stories of a lonely boy named Elliott — played by Henry Thomas — who befriends a harmless alien, dubbed E.T., who’s stranded on earth. It’s a race against time, parents and the government as Elliott attempts to help E.T. phone home and reunite with his own kind.
