This document discusses and compares the marketing of several films:
1) Captain America had very successful marketing due to its connection to the Avengers franchise and large comic book fan base. Extensive marketing included posters, websites, trailers, and TV ads.
2) The marketing for The Thing was also extensive, but it failed to attract audiences due to competition from other popular films and a lack of recognizable stars and brand.
3) 50/50 used star Seth Rogen to attract both comedy and drama audiences by blending humor with the serious topic of cancer. This diverse marketing approach helped make it a successful film.
