How effective is the combination of your main product and ancillary texts?

When creating the trailer we were thinking about the ancillary tasks and how scenes in the trailer could be connected to the poster and possibly be discussed in the trailer. When we found out we were just making a front cover I figured a photo shoot would work just as well and used a nice picture outside with the star of the film and the main character in the trailer. The poster worked well because I could link the lockers that were in the trailer, and which can be linked back to the school, with the poster so the trailer and the poster anchor each other. The poster had a puff on it that said it could be the best romantic comedy of the decade which was quoted by Exposure magazine, the magazine that I used as my other ancillary text anchoring them together as well.
