Star Wars: The Force Awakens did release its first teaser trailer in November of 2014, more than a year before the film debuted, but considering it was the first Star Wars movie in years, a little extra push is to be expected.
This was then followed by a full trailer for Star Wars; The Force Awakens that arrived in October, less than two months before the movie would hit theaters.
The film then released a second teaser in April of 2015, during Star Wars Celebration that year.
