The best would probably be to call Ambler Theater to know when a particular film will be being screened there. If you're looking for showtimes for films already playing, Google has the them built into it's search engine. Lastly, you can drive or walk by the theater and look at the marquee for showtimes.
It's best to call, or drive by. Posted screening times in the newspaper or online can be wrong in my experience.
