The Holywood man stars in the film adaptation of E.L. James' erotic bestseller as the playboy billionaire Christain Grey.
The much anticipated film will be released in cinemas on Valentine's Day 2015.
The official trailer was posted on to the film's Twitter page on Thursday.
This is the first time fans have had a taste of Dornan as Grey, with only teasers being previously released.
In the poster for the film Dornan is pictured from behind looking out over the Seattle skyline with the words: "Mr Grey will see you now".
Fifty Shades of Grey also stars US actress Dakota Johnson as timid student Anastasia Steele and pop star Rita Ora, who plays Grey's adopted sister Mia.
The movie, which was filmed in Vancouver, is directed by Sam Taylor-Johnson.
It is set to be a busy year for Dornan, who was recently in Belfast to film the second series of crime thriller The Fall.
