(CNN) -- "Star Wars: Episode VII - The Force Awakens" director J.J. Abrams has come up with a nostalgic way to reveal the names of the movie's characters.

We've known for months that "The Force Awakens" features fresh faces like John Boyega, Daisy Ridley and Oscar Isaac. We even got to see them in action in the movie's first trailer, which was released the day after Thanksgiving.

But the lingering mystery was who exactly those actors are playing. Now, thanks to some clever retro-style trading cards, we know the names of their characters.
