Just for Laughs, the Belfast Free Library’s summer comedy movie series, continues Sundays at 7 p.m. through Labor Day weekend. Admission is free for the screenings in the downtown library’s Abbott Room. The series spans four decades, starting with the 1970s, and features a wide variety of Hollywood’s most memorable comedies, along with some of the funniest actors and actresses to ever grace the silver screen.

On Aug. 5, the series will screen “The Princess Bride,” the popular 1987 romantic, comic adventures of Buttercup (The Princess Bride) and her hero, Westley, complete with kidnapping, giants, evil villains, swordplay and unbridled laughter.

On Aug. 12, the series screens “Silver Streak,” and an uproarious whodunit from 1974. Gene Wilder and Richard Pryor team up to catch the murderer of an art historian killed on the iconic cross-country American train — think “Murder on the Orient Express” meets “North by Northwest,” a lot funnier. The comedy-thriller also stars Jill Clayburgh and Patrick McGoohan.

“Little Miss Sunshine” (2006) on Aug. 19 offers the ultimate dysfunctional family in the Hoovers. Olive (Abigail Breslin), the pudgy 7-year-old daughter, has just become a beauty pageant finalist so the family, including Steve Carell and Alan Arkin, take an 800-mile trip to in their VW Microbus.

“The Freshman” (1990) has Marlon Brando give his Godfather role a comedic turn as he makes an offer to freshman student Matthew Broderick that he can’t refuse — all the young man has to do is run a few small errands for a lot of money. Komodo dragons, Bert Parks and lunatic girlfriends all play into to this one-of-a-kind farce.

Sept. 2’s “The In-Laws” (1979) caps the series with a renowned Hollywood comedy. What do a well-mannered podiatrist (Alan Arkin) and a crazed CIA agent (Peter Falk) have in common? Nothing, except that one’s daughter is about to marry the other’s son. First, though, there is a crazy international chase involving stolen jets, arms smuggling and banana republics.
