>>79595547>if Deadpool manages to be a huge successhttp://www.the-numbers.com/market/mpaa-rating/R-(US)It won't. It's true that comedies are among the best performing R-rated movies of the past few decades, but the top performer was a religious movie and there's a 40% drop from the biggest earner before you hit the first actual comedy, and the gulf between the lowest and highest earners is huge.
It's also worth noting that #25 on that list, Terminator 3, is a financial flop - partly because it had a high budget, partly because they paid so much to Arnie; but that's the problem with hoping Deadpool would even place that high. It doesn't have a big name attached, unlike almost all of those movies at the time they were released. So really Deadpool is reduced to being The Hangover with superheroes, only they're not heroes, and the lead is a guy who's so background if his performance in this movie were nominated for awards it would be as best supporting actor.
What's possible is that Deadpool will make modest amounts of money - R-rated movies generally don't, but let's assume it has goodwill - and on a shoestring budget, like Kick-Ass, will get a sequel with the same kind of budget and probably the same kind of performance. We're talking under $200m worldwide gross. What's not possible is that it will lead the X-Men franchise.
