Ryan Reynolds was offered to voice act for Deadpool, his role in the movie X-Men Origins: Wolverine (2009), but due to the negativity towards the movie and Deadpool's portrayal in it, Ryan Reynolds declined, and Steve Blum got the part as Deadpool.
In the cutscenes when Logan is shown in the not too distant future, the jacket he wears that is torn up, is his X-Men jacket from the film X2: X-Men United (2003) and X-Men: The Last Stand (2006).
A version of the game is much more violent than the associated film X-Men Origins: Wolverine (2009).
The developers made sure to be faithful to the Wolverine comics.
