how long is previews at the movies

Movie previews, also known as trailers and ads, typically last 15 to 25 minutes before the main feature starts, depending on the theater chain and film type.

Standard Duration

Major chains like AMC, Regal, and Cinemark run previews for about 20 minutes on average, featuring 5-8 trailers (each 1.5-3 minutes long) plus promotions. This excludes initial ads or warnings, which can add a few extra minutes. Showtimes listed online mark the feature film's start, so arrive 20-30 minutes early to catch everything.

Variations by Theater and Film

  • Blockbusters (e.g., Avengers: Endgame) often get longer reels up to 25 minutes to build hype with Marvel teasers.
  • Indie or smaller films (e.g., Parasite) stick to 10-15 minutes, focusing on niche trailers.
  • Recent trends show some theaters extending to 25 minutes, sparking complaints on forums like Reddit's r/Cinemark about mismatched genres (horror trailers before comedies).

Chain/Film Type| Typical Preview Time| Examples
---|---|---
AMC (general)| 20 minutes| 5-8 trailers 3
Regal Cinemas| 15-20 minutes| 2-5 min per trailer 9
Cinemark (recent)| Up to 25 minutes| User reports, Feb 2025 4
Blockbusters| 20-25 minutes| Endgame 1
Indies| 10-15 minutes| Parasite 1

Why the Length Varies

No regulations cap previews; studios and theaters decide based on marketing needs, like promoting upcoming releases or local ads. Arriving late risks missing the start—many regret skipping, as trailers often spotlight must-sees. Pro tip: Check theater apps for "true start time" features some chains now offer.
