“Atlanta” breakout Zazie Beetz will play Domino in “Deadpool 2.”

“Deadpool” star Ryan Reynolds made the announcement by tweeting “domino effect,” along with a photo that spelled out the actress’ name with — you guessed it — dominoes.

In the the Marvel comics, Domino is a mutant with telekinetic powers in the mercenary group Six Pack and later X-Force. Her partner, Cable, has yet to be cast.

Beetz is best known for her role as Van in FX’s critically acclaimed comedy “Atlanta,” playing Donald Glover’s best friend and the mother of his baby daughter. The show won two Golden Globes, including one for Glover, this year.

Beetz, repped by Gersh, will also appear in “Slice” this year alongside Chance the Rapper.

“Deadpool 2” will be directed by “John Wick” helmer David Leitch, who took over the director’s chair after Tim Miller dropped out last October due to creative differences with Reynolds. Original screenwriters Rhett Reese and Paul Wernick are returning to pen the sequel.

Fox recently teased the film with a short before showings of Hugh Jackman’s “Logan.” Reynolds later posted the clip — a cut scene from the movie — on his YouTube page.

The cheeky scene shows Reynolds’ Wade Wilson going into a phone booth to get suited up — and mooning the audience in the process — in order to save an elderly man being robbed at gunpoint. The man dies, unfortunately, by the time our hero is done changing.

“Deadpool 2” is expected to hit theaters on March 2, 2018.
