When it was first announced that a new Godzilla movie was in the works, many people had flashbacks to Roland Emmerich's critically savaged 1998 blockbuster. Legendary Pictures and Warner Bros. had to make it very clear that their version of Toho's most famous son was an entirely different beast,. What better way to make their intentions instantly clear to general audiences than by releasing a teaser trailer that is nothing short of jaw-dropping?
Runner Up - Guardians Of The Galaxy First Trailer
Guardians of the Galaxy was a movie based on a comic book that most general audiences had never heard off, featured an ensemble cast with little in the way of star power and was Marvel Studios' biggest gamble to date. When people were unsure what to make of the movie the first trailer did everything that Marvel wanted it to do; introduce the characters, establish the premise, give a hint of the epic scope and most importantly, showcase the movie's off-kilter sensibilities and rich vein of humor.
