Deadpool 2: 9 Most Likely Secret Cameos

5. Ryan Reynolds

Thanks to the wonderful quirk of Deadpool's fourth-wall-breaking shtick, we could see the second strangest cameo in movie history (after Arnold Schwarzenegger almost met himself in Last Action Hero). And it would definitely fit with the first movie's affectionate roasting of Ryan Reynolds for the real-world actor to appear as himself alongside his outrageous character alter-ego.

The first movie was full of jokes at his expense and the fact that it was Reynolds himself who came up with some of the most self-deprecating - on top of him insisting on the Green Lantern joke - would offer an easy route for an even more direct roast.

It would be the most Deadpool thing ever to have the character interact with the actor beneath the mask and it would be further reminder once more that he's just not like other superheroes. And just imagine how much fun Reynolds would have.
