Teaser trailers I find effective

I find this teaser trailer effective as it doesn't give away the story line therefore sticking to one of the conventions whilst still being able to introduce the characters and advertise the film. This allows the audience to re-familiarise themselves with the characters as they are already known to the target audience.

The reasons I find this teaser effective are similar to the reasons for the Toy Story 3 trailer; however I find this one more intriguing is that we don't know any of the characters before this trailer and we still don't learn anything about them. The final reason I like this trailer is that the music in the background is quiet and minimal and only increases when important text is placed on the screen.

The reasons I like this trailer is that even though it uses a lot of speech during the film it gives very little of the plot away and just makes the audience question what they're watching. Also the way the speaking being used over the top is effective as it implies explanations of the speech by the shots shown.

The final teaser trailer is Harry Potter and the Order of the Phoenix. The reason I chose this trailer is because it gives enough information to make the audience want to watch the film without giving away all the details of the plot. Also the use of the dramatic iconic music, builds the tension without taking away from the speech that is laid over the top.

All of these trailers are effective as they all follow different conventions of teaser trailers, matching the information I have recently learnt about trailers.
