“My Big Fat Greek Wedding 3” - ( PG13; 1 hour, 32 minutes) -  “My Big Fat Greek Wedding 3” is uproarious with much of the same family comedy and joy that made the first and second movies stand out. The films have always had beautiful and ahead-of-their-time messages for audiences about cultural acceptance, heritage, and tradition, as well as women's rights. In the third film, the Portokalos family takes a trip to Greece for a reunion with their extended Greek family—the final wish of patriarch Gus, who has passed away. (Played by Michael Constantine who passed in 2021.) While Toula and Ian search for Gus's childhood friends, love blossoms between Aristotle and Paris (an unwelcome development to Paris, who ghosted Aristotle before the trip), and Aunt Voula continues to be Aunt Voula, the most hilarious member of the Portokalos family. Final screenings at 7 p.m. Wednesday, Sept. 20 and Thursday, Sept. 21.

“Jules” - (PG13; 1 hour, 27 minutes) - Opening night, Friday, Sept. 22 is Family Night!  Family admission (up to 5 people) is $20 plus one FREE large popcorn! Jules follows Milton (Ben Kingsley) who lives a quiet life of routine in a small western Pennsylvania town, but finds his day upended when a UFO and its extra-terrestrial passenger crash land in his backyard. Before long, Milton develops a close relationship with the extra-terrestrial he calls “Jules.” Things become complicated when two neighbors (Harriet Sansom Harris and Jane Curtin) discover Jules and the government quickly closes in.
