Choose a movie times website on the Internet. There are many good options that will give extensive lists of theaters and movie times. For our purposes here, we'll be using moviefone.com, but feel free to substitute one of your choosing.
Enter your zip code in the box labeled "find movie times" in the top-right corner of your screen and press "Enter." This will pull up a list of local movie theaters.
Scroll through the list and familiarize yourself with the movies playing in theaters. Regular theaters will be playing many of the same movies, so take note of which films are being listed again and again. This will help you to notice when you come across a theater with a completely different list. Also pay attention to the names of theaters; sometimes, dollar movie theaters will have names that identify them as such.
Identify theaters that seem like dollar movie theaters. Use the provided contact information to call the theater in order to confirm that it is, in fact, a dollar movie theater.
