In the opening 4th wall breaking quote of "Deadpool" film, Deadpool tells the audience:
I know right? You're probably thinking, "Whose balls did I have to fondle to get my very own movie"? I can't tell you his name, but it rhymes with "Polverine."
I know the usual explanation is that it's meant as a poke at the studio (and the difficulty of having a solo Deadpool film), but it seems rather weirdly worded for that purpose - neither Wolverine (the fictional character), nor even the actor playing him (Hugh Jackman) have absolutely any control over which movies get made - the studio execs decide that, or the producers.
So what does "Wolverine" have to do with this?
I'd prefer answers based in canon (canon includes interviews etc...) over speculation.
