Check out trailer for Creed II (video)

As an extension of the Rocky movie universe, Creed was a surprisingly great commercial and critical success in 2015. A sequel seemed inevitable, and that's what's coming this fall.

Sylvester Stallone has teased the storyline for Creed II, with the return of Dolph Lundgren as the infamous Ivan Drago from Rocky IV and a hint Drago's son would take to the squared circle against Adonis Creed (Michael B. Jordan) in the Creed sequel.

Stallone teased the release of the Creed II trailer on Monday, but only the movie poster came out on Tuesday. On Wednesday morning, after a re-confirmation of when it would come out, the first official trailer was released.

Boxer Florian Munteanu will play Ivan Drago's son in the film, with Tessa Thompson and Phylicia Rashad returning to their roles from the first one. Creed II will hit theaters on Nov. 21, just in in time for Thanksgiving weekend and the holiday season.
