Iron Man (2008)

Arguably the best Marvel flick to date, Iron Man also had one of the best first trailers ever "“ with the simple tagline, Heroes are built. The trailer was even more surprising, if we take into consideration the names involved "“ Jon Favreau as director (known just for comedies) and Robert Downey Jr. in the lead role (known mostly for his erratic and problematic behavior).

But Marvel struck gold! Who would have thought that Iron Man would work? Well, the trailer might have been the best sign that it will. With an awesome soundtrack, it perfectly captured who Tony Stark is in the comics "“ an eccentric guy with a more than problematic behavior. Coincidence?

With a hint at bigger and more iconic villains, a giant Iron Monger, and an extra-cool scene involving a tank, this trailer might just be called perfect!
