Social media and websites, this is the best place to find any trailer as it spreads across these platforms very quickly, they can also be shared through social media becoming accessible to other people.
Character introductions, main characters are usually shown the most in the trailer, there is the idea that trailers give away too much, they mostly include sequences with the main characters doing something or reacting to something.
Music and Voice overs, there is usually a lot of music and voice overs in the film trailers, usually the voice over is one of the main characters talking, for e.g. in the new Star Wars: The Last Jedi, one of the main characters is talking over the trailer and he mostly talks about what will happen in the film without giving away too many spoilers, therefor generating a lot of excitement for the film.
On screen text is included in most trailers, they are usually the names of the actors and the production companies, also on screen text is used to credit the editors, producers, screenplay by and many more, it is also used to say what else the producers could have been included in, and or showing what awards either the producers have won or what the actors have won, for e.g. best Male/Female actor.
Name Captions is similar the onscreen text, this is only used for crediting the producers, editors and will be used to name the actors included in the film and film trailer.
Taglines are used to emphasise a point about a film as well as hint what will happen in the film for the audience. A great example of using a tagline is Alien "In space no one can hear you scream". A tagline aims to be very memorable to the audience, Alien's tagline is truly perfect as anybody who has seen the film can remember the tagline, it is a rather scary tagline to use and using it in a trailer and poster definitely creates this horror and tension in the audience, even before they have seen the film.
Release Dates are used in trailers to generate excitement in the audience, a lot of distributors will chose to reveal the confirmed release date in the trailer but instead of revealing the date many trailers will use 'Coming Soon' instead to generate curiosity and excitement, however saying this can also lose an audience as they wont want to wait a very long time for a film as they can easily forget about said movie.
Company info, every trailer will include the companies institution, examples are Warner Bros, Disney, Lionsgate etc. this is done so the audience know who is associated with the film, this can attract large audiences who are fans of the companies, just because they are involved in the production of the film.
From the director of is used a lot in film trailers, this is because it is a good way to show a directors success, if the trailer includes the from the director of, for example The Avengers then the audience can already assume it will be a high budget, exciting film due to the success of the Avengers franchise, depending on the film and the genre, trailers can include different films to show off a directors work.
Time/Length, the length of a film trailer that is allowed by the MPAA is 2 minutes and 30 seconds, during this time the trailer has to draw in an audience, generate excitement and possibly create a fan base, the more people the trailer can draw in the more successful the film may be.
