At this stage, it's weird that Deadpool 2 remains mostly a mystery. While Fox has committed to the sequel (which was a no-brainer after the first one became the highest grossing X-Men franchise film earlier this year), the project still doesn't have a release date, and no firm details regarding casting. Of course, just because we don't have any official details doesn't mean that rumors haven't been flying around all over the place -- and today we have a report suggesting the production is looking at six actresses to play the role of Domino.
Domino

It hasn't even been confirmed that Domino will be a character in Deadpool 2 yet, but Collider claims to have a source close to the production who has fed them a list of names currently being tested for the part. A few months ago it was said that Mackenzie Davis was being eyed for the role, but she isn't included amongst this new batch...

Lizzy Caplan

First up we have Lizzy Caplan, who has been known to bounce back and forth between movies (The Interview, Now You See Me 2) and television (Masters of Sex, Party Down). While she doesn't really have much ass-kicking experience on the big screen, one thing she definitely brings to the table is a sense of humor, as she has certainly proven to be equally adept at being both a dramatic and comedic performer.

Mary Elizabeth Winstead

Unlike Lizzy Caplan, Mary Elizabeth Winstead does have some comic book movie experience -- having played Ramona Flowers in Edgar Wright's Scott Pilgrim vs. The World - and she would certainly be a great fit to play Domino in Deadpool 2. She has proven time and time again in an extremely wide variety of projects that she is a talented star -- and that extends to her role earlier this year opposite John Goodman in 10 Cloverfield Lane.

Sienna Miller

Sienna Miller is much better known for her dramatic work in films like American Sniper and Foxcatcher, but she did dabble a bit in action blockbusters when she took on the role of the Baroness in 2009's G.I. Joe: The Rise of Cobra. We probably shouldn't talk about how that movie turned out... but one thing also worth mentioning is that Miller is the only actress on the list who has previously worked with Deadpool star Ryan Reynolds (they were both in 2015's Mississippi Grind).

Sofia Boutella

In the world of action movies, there are few stars rising as fast as Sofia Boutella, so it wouldn't be a huge surprise to see her take on the part of Domino in Deadpool 2. She broke out thanks to her ass-kicking performance in Matthew Vaughn's Kingsman: The Secret Service, but continued to earn acclaim thanks to her part as the alien Jayla in Justin Lin's Star Trek Beyond. She would certainly be a fit for director Tim Miller's upcoming blockbuster

Stephanie Sigman

Stephanie Sigman is not nearly as well-known as some of the other names on this Deadpool 2 list, but she has certainly been getting more attention in recent years. She first really earned notice thanks to her performance in Gerardo Naranjo's 2011 film Miss Bala, but she has since been in a Bond movie (featured in the opening sequence of Spectre) and more recently has been playing Valeria Velez on the Netflix series Narcos.

Sylvia Hoeks

Like Stephanie Sigman, Sylvia Hoeks may not be a name that you recognize now, but there is a very good chance you will in the near future. The Dutch actress hasn't done a great deal of work in America just yet, but has recently landed a high-profile gig, as she has a part in Denis Villeneuve's in-production Blade Runner 2049. If that movie doesn't make her a star, playing Domino in Deadpool 2 would.
