Just a few more sleeps before $3 movie day happens. The big summer movies are done and this is a slow time for movie theaters until Thanksgiving. They don't want the theaters to be empty until then. They barely survived the pandemic.
So AMC, Regal Cinemas, and many other chains will offer $3 movie tix on September 3rd (Saturday) for all movies in any format.
It's their hope that you'll come in, buy some snacks, and make plans to come again. Before the movie you paid $3 to see, you'll see a glimpse of all the movies coming out soon (Wakanda Forever, Avatar 2, etc).
