The filmmakers have increased the attention towards teasers and trailers like never before. Earlier, teasers or trailers of movies used to be just for the sake of it to give a glimpse about the movie. But now, they are being promoted aggressively by PRs and the makers are even paying for views on YouTube with ads. With all these, the trailers can get millions of views, but they can’t make the audience click the like button unless the trailer impresses them. There are few movie teasers that impressed millions and recently the teaser of KGF2 has got 1 million likes in just 1 hour 17 mins. Take a look at all such trailers/teasers that were the fastest to reach 1 million likes mark on YouTube.
