The movie is based on Molly Bloom's book detailing her time hosting high stakes poker games for the likes of Ben Affleck, Leonardo DiCaprio and Tobey Maguire.
Now Deadline is reporting that Robin Hood and Untouchables star Kevin Costner is finalising a deal to appear in the film.
No word yet on the role the Oscar winner is set to take, but with an already stellar cast this is starting to look like we potentially could have the next great poker movie since Rounders in the making.
