Thank you 300: Rise of an Empire for reminding us what trailers are for.
Give a little bit of the story, just enough to catch your attention. Throw in an important moment for at least one of the actors, this time being Lena Headey.
Add in action and fighting enough to get the heart racing and just like that, people are excited for the movie and you've expended a minute's worth of screen time.
Check out the almost perfect 300: Rise of an Empire international trailer below!
