In Marvel's comic book mythology, Domino is a mercenary who mostly works on the side of the good guys. Debuting in the same issue as Deadpool himself (1991's New Mutants No. 98), she is another survivor of a government program to create the ultimate soldier. Instead of adamantium claws or hyperactive healing powers, she can affect probability itself, creating "good luck" for herself and those around her — something she's put to use serving alongside Cable, another fan-favorite X-character who will be showing up in the new movie, but has yet to be cast.

Producers were looking to specifically cast a black or Latina actress in the role of Domino, testing a variety of actresses, but appear to have landed on Beetz.

Deadpool 2 will be directed by John Wick filmmaker David Leitch, with original Deadpool scripters Rhett Reese and Paul Wernick returning to pen the follow-up for Fox, along with The Martian writer Drew Goddard. Simon Kinberg, Lauren Shuler Donner and Reynolds are set to produce.

After its February 2016 release, Deadpool became a runaway hit (and a surprise awards contender), grossing more than $780 million at the global box office and prompting the studio to expedite production on a sequel.

Beetz plays Van on Donald Glover's award-winning FX series Atlanta, where she has emerged as a fan favorite. The actress will soon be seen in Chance the Rapper's horror-comedy Slice. She is repped by Gersh.
