The next time you see a movie at AMC Theatres, note that your movie may not start at its listed time.

Have you ever sat down for a 6 o’clock movie and felt like the movie didn’t actually start until 6:30? You’re not alone! And AMC has now issued a statement addressing that.

In a recent change, AMC Theatres is warning customers that their movies may not actually start at their listed showtimes due to extra ads.

Here’s what you need to know about the change.

What is changing about AMC Theatres’ listed start times?

There is now a disclaimer towards the top of the screen when you buy tickets that says, “movies start 25-20 minutes after showtime.”

This gives an estimate of what AMC Theatres has been doing with their pre-show ads and trailers, but this new disclaimer now gives customers notice in case they want to arrive later when the movie starts.

AMC Theatres will also show even more ads in the run-up to its movies, including up to 5 minutes of ads after the movie’s stated start time. This decision is part of the company’s agreement with the National CineMedia ad network to include extra commercials ahead of the trailers.

Plus, the theater chain plans to air a 30-to-60-second “Platinum Spot” before the last one or two trailers. This special slot isn’t just for movie trailers; other theater chains like Regal and Cinemark have had NCM Platinum Slots for major retailers and brands, like Google, Jeep, and E.L.F. Cosmetics.

Previously, AMC rejected this ad slot as the company believed it would be perceived negatively by moviegoers. Five years later, AMC has reversed this decision due to finances and told The Hollywood Reporter, “While AMC was initially reluctant to bring this to our theaters, our competitors have fully participated for more than five years without any direct impact to their attendance. This is a strong indication that this NCM pre-show initiative does not negatively influence moviegoing habits.”

What does this actually mean for AMC moviegoers?

The long and short is, AMC will be showing extra ads ahead of movie start times and will have a premium slot toward the end of the trailers.

Those first ads might also run a few minutes past the start time, then you’ll have to allot time for trailers for upcoming movies, a “Platinum Spot” ad, and the standard two AMC Theaters promotional videos, like the famous Nicole Kidman “We Make Movies Better” ad.

Altogether, that accounts for about 25 to 30 minutes. So, a 6 p.m. movie really might not start until 6:30 p.m. now.
