In its Centennial Celebration year of sampling 100 years of movies, the downtown Colonial Theatre’s travel-through-the century free film series has landed in the vicinity of 1975.

On Tuesday, Aug. 14 the Colonial offers a choice of two features to be shown after the current movies; those play around 7 p.m., so the free movies will screen around 9 p.m. — check the movie schedule for exact times.

The Aug. 14 movies are “Jaws” and “Monty Python & the Holy Grail.” “Jaws” is the premier summer blockbuster, of extra interest this summer of White Shark visitations to Cape Cod. It stars Roy Scheider, Richard Dreyfuss and Robert Shaw under the direction of Steven Spielberg plus that famous John Williams score. In the classic Monty Python feature, Terry Gilliam directs a “movie of 1000 quotes,” an absurdly British, wacky take on the middle ages and King Arthur’s legend.

On Tuesday, Aug. 21, the free films will screen before current features: “All the President’s Men” at 4:15 p.m.; and “Chinatown” at 4:30 p.m. History comes alive in “All the President’s Men,” a truth-is-stranger-than fiction story of the Watergate scandal; Robert Redford and Dustin Hoffman portray the crackerjack reporters Woodward and Bernstein. Roman Polanski’s direction of “Chinatown” results in perfectly wrought noir thriller starring Jack Nicholson, Faye Dunaway and John Huston and a non-Hollywood ending gave this picture great success when released.

In September, the series will move up to 1984.
