All three of my products share certain traits and attributes.

The beach is a running theme, appearing heavily in the trailer and also in the background of the poster.

The main character appears on/in all three of my products; he is the only character on the poster and magazine and he has the most individual screen time in the trailer.

All products feature some sort of dark imagery; the dark background on the magazine, the stormy beach in the background of the poster and the violent imagery of my trailer. For these reasons, I believe my trailer and ancillary tasks work well together and that the combination of my main product [trailer] and ancillary tasks [poster and magazine cover] is effective.
