I don't think so. Thor, Cap Am both opened modestly and didn't make much of an impact the BO. That gives you a rough idea of the kind of figures Avengers will pull in. People will see Cap Am, Thor, Hulk ( Hulk especially might turn out to be a negative, I know very few people who liked either Hulk movie, if they see him, I can guarantee it will turn off a number of people...) and think why do I want to see this when I couldn't be bothered to watch the standalone movies? It doesn't help that both trailers have been very dull/flat. There's just very little hype for the movie outside of message boards and fansites.
Unlike The Dark Knight Rises, where the teaser created a tremendous amount hype with people talking about for weeks afterwards. I still remember the crazy hype the day after it was released, people were watching the trailer on their phones, talking about who the big guy with the mask was, why Bats looked so scared/beaten...I can't think of a single time I've heard of anyone mention the Avengers trailer/movie.
We'll see. Opening weekend will set the pace - 60-70m and it will be downhill from there.
It looks cheap, tacky and something he threw together on a $10 dollar budget. Not something an expert bowman would ever use.
