John McClane is Bruce Willis...of all the characters mentioned McClane is the one that is most identified by the actor who played him and Die Hard as a movie franchise is all Bruce Willis too. I don't think it is as easily transferrable as any of the other movies or characters mentioned.I really don't see all the Mission Impossible mentions. Yeah, maybe the concept of the franchise has more longevity to it but as a character McClane is far more timeless than Hunt, a pretty bland character that's been carried by Cruise's star power since day one. There are no complexities to the character outside of the wife they don't even pretend he has anymore.
And I wouldn't call Ethan Hunt bland but he is a less defined character which I think would open him up to other interpretations much easier than the other characters plus the whole concept of the Mission Impossible move franchise would be easier to just transfer to another actor.
