Proforma: First sight of the main character/s

I am interested in when comedy film trailers reveal the main characters to the audience. This is an important moment for the film itself as this is the audience's first view of the characters in the film and how funny the film could be. I will look at 9 recent comedy trailers and see at what point in the trailer they reveal the characters to the audience which will give me an idea how much of a build up I should give the trailer before showing them to the viewers.

Inbetweeners: After 14 seconds all characters are shown together
StepBrothers: 20 seconds
21 Jump Street: 6 seconds
Ted: 30 seconds
SuperBad: 8 seconds
Role Models: 8 seconds
Kick Ass: 20 seconds
Hallpass: 25 seconds
Horrible bosses: 45 seconds

In most action trailers such as James Bond, the main character is introduced to the audience after showing clips of the country the film is based in and usually the supporting cast as well to help build tension and a scene for the for the main character. Where as in comedy film trailers, the main characters are introduced into the trailer almost immediately. This helps show the audience that the main point of the film is about the jokes the characters are cracking instead of the surrounding background they live in. It also helps the first impression of the film if the trailer immediately makes all of the audience laugh.

Some key and different points I have noticed in some of these trailers is the start kicks off with music that brings action into a film trailer, and then for it to all stop for a joke. This is a good effect as the film trailer almost shows the audience that it's going to be an action packed film and then changes the genre completely. This helps the impact of the joke using the element of surprise. This is a technique I could use at the beginning of my film. Almost every trailer also started off with the age certificate of the trailer before showing the trailer itself. This is done to prove a point to the audience that what they're about to see is suitable for them. I should consider adding this in to make my trailer seem more realistic. A few of the trailers also have a lot of sound effects added when the title of the film appears on the screen. This is to attract attention and to build the scene for the rest of the trailer. I will search around and try out a few music effects so when my title of the film bursts in, it sounds like an explosion or something to impact the film into being over the top and comical.
