* TheOtherMarty: Deadpool was originally voiced by someone working for The Ocean Group, but the producers didn't feel he worked very well. They then brought in Creator/NolanNorth (who was already working for them in ''WesternAnimation/WolverineAndTheXMen'') and had him improvise lines for Deadpool.
** ThrowItIn: Most of North's dialogue for Deadpool was improvised as a result.
* WordOfGod: The producers have said that the "Wolverine" short, ''WesternAnimation/WolverineAndTheXMen'', and ''WesternAnimation/AvengersEarthsMightiestHeroes'' take place in the same universe. However...
** GodNeverSaidThat: They said no such thing about the "Thor" short.
