A film's trailer always plays a very important role. After all its the very first peek into the cinematic world of a film. Usually, the sneak peek is barely for 2 minutes and a few seconds, but there have been instances and films that didn't hesitate to get generous with their film trailers and gave the audiences a better first look at their film's world. Here are 5 movies which broke the record with the longest trailers in cinematic history...

1. Ambience (7 Hours, 20 Minutes)

Yes, you read that correctly. Swedish filmmaker Anders Weberg created an experimental film called Ambience that was 720 hours long. In 2016, Weberg released a "short trailer" that clocked in at 7 hours and 20 minutes—all filmed in a single, continuous, dialogue-free take on a beach. 

2. The Girl with the Dragon Tattoo(8 Minutes, 6 Seconds)

When David Fincher tackles a project, he doesn't compromise. To build hype for his pitch-black, brilliant 2011 adaptation, Sony released an "extended character profile" trailer that ran over eight minutes long. Instead of just flashing quick jump-scares and explosions, Fincher used the luxury of time to let the cold, tense atmosphere sink into the audience's bones, treating the trailer like a standalone short film.

3. Singham Again (4 Minutes, 58 Seconds)

Rohit Shetty's cop universe is famously loud, grand, and unapologetically massive. For Singham Again, the creators decided that a standard teaser simply couldn't hold the sheer amount of star power and explosive action they had cooked up. Clocking in at just 2 seconds under five minutes, this trailer felt like a mini-epic, laying out high-stakes family drama, flying cars, and intense monologues before the movie even hit theaters.

4. Welcome To The Jungle (4 Minutes, 10 Seconds)

When you have a massive ensemble cast featuring what feels like half of Bollywood, a two-minute trailer just turns into a blur of faces. Welcome To The Jungle took its time—four minutes and ten seconds, to be exact—to introduce its chaotic world, massive musical numbers, and a sprawling cast of characters. It’s a preview that gives you a full workout just keeping track of everyone on screen.

5. Dhurandhar (4 Minutes, 8 Seconds)

Rounding out our list is Dhurandhar, another textbook example of a film trying to pack heavy narrative weight into its opening pitch. At over four minutes, the trailer demands a genuine commitment from the viewer. It’s proof that sometimes, filmmakers simply have too much story to tell to be bound by a 120-second timer. Which trailer from these are you yet to watch?
