Is it because of Deadpool why u think Ryan should be billed first. It's just right that Jake should get the 1st billing cause really he is the biggest star.Goodness i don't even think this is debatable. Obviously you're not aware of his resume.

The biggest star there is Jake G. Ryan is also a big star , but Jake G's star is different, more like leaning towards Dicaprio level esp acting-wise maybe much more.He chooses his roles and movies wisely. I was surprised that he made this one, maybe for fun and for a change. And very handsome.

I'll watch this coz Jake G is here. This is not usually the type of movie he makes , and I'm not into this type of movie either,but i will still watch it coz The Great Gyllenhaal is here.
