As the downtown Colonial Theatre travels through this, its 100th, year sampling 100 years of movies, owner Therese Bagnardi has found it as hard as ever to pick only a few movies to present. In her latest announcement, she reminded movie fans that it pays to visit Opera House Video on Church Street to decided which screening to attend.

“All movies we have played in this year’s series, and tons more, are only a rental away from being enjoyed by you at home on your TV screen — just sit up close so it seems bigger,” she said.

The free series moves back to Monday nights this month, offering two nights of two movies Sept. 17 and 24. On Sept. 17, the Colonial will screen “Sophie’s Choice” from 1982 and “Ghostbusters” from 1984. In “Sophie’s Choice,” starting 7 p.m., a luminous Meryl Streep gives compelling tour-de-force performance as an Auschwitz survivor in a powerfully haunting and wrenching drama adapted by a William Styron novel. Kevin Kline co-stars. At 7:15 p.m., “Ghostbusters” answers the question of who you gonna call? with Dan Akroyd, Bill Murray, Sam Raimi, Ernie Hudson, Sigourney Weaver, Rick Moranis and a bevy of oddballs from the spirit world.

On Sept. 24, the free movies are “Blade Runner” (1982) at 7 p.m. and “The Big Chill” (1983) at 7:15 p.m. Ridley Scott directs Harrison Ford in the blueprint for modern sci-fi, a visually stunning, hard-boiled morality play that is a noir take on 21st century dystopia where commercialism and biotech run amok. Note that the Colonial is screening the Director’s Cut, which lacks the voiceover (and cheerier ending) of the theatrical release.

With the soul-searching premise of boomers reunion at a friend’s funeral — and an iconic soundtrack, “The Big Chill” is a ‘60s nostalgia trip that strives to define a generation. The superb ensemble cast includes Glenn Close, William Hurt, Kevin Kline, Jeff Goldblum and, yes, Kevin Costner, making a fleeting appearance in the opening credits.
