As the film’s March start-date looms closer, things are (finally) coming together for the Deadpool movie. Ryan Reynolds has long been attached to play the antihero Marvel character, but 20th Century Fox only recently greenlit the film with Tim Miller making his feature directorial debut. Now, as casting is underway, THR reports that Gina Carano has signed on to star opposite Reynolds in the film. The former mixed martial artist has been ramping up her acting career as of late, impressing as the lead in Steven Soderbergh’s action pic Haywire and also appearing in Fast & Furious 6.

In Deadpool, Carano will play a character called Angel Dust, who in the comics was part of the underground mutant group known as the Morlocks. Since Deadpool takes place in the X-Men universe, THR also confirms another familiar character will also be appearing: Colossus. The Russian mutant is slated to play a role in the story’s proceedings, but the specifics are being kept under wraps.

Additionally, THR reveals how Deadpool’s origin will be dealt with in the film. In this iteration, Reynolds plays an assassin dying of cancer who undergoes a procedure that is supposed to cure him, but instead leaves him twisted and scarred, though also imbued with super-powers. In the comics, this procedure was performed as part of the government’s Weapon X program.

The report also notes that T.J. Miller’s (Silicon Valley) deal has apparently closed, as he is confirmed to have a supporting role in the pic as some comedic relief. While Deadpool is barreling towards a February 12, 2016 release date, THR notes that Carano will first shoot a role in the Bruce Willis-fronted action movie Extraction.
