Rumor has it that DC is breaking out these two for a super-hero buddy copy movie to be released next year (I think).
Foremost, these two have some of the coolest costumes in the super-hero industry. They just look cool, the color, the design. All of it.
Secondly, I'm not sure they can carry their own movie.
Third, I know they can.
IF they did this right, styling it like the just released Ant Man, then it has a real chance. Buddy cop movies are a long tradition but aren't, for the most part, that good on the screen. The ultimate has to be Running Scared. That movie captured the perfect mix of comedy, serious, action, drama and everyone was an understatement of their character, meaning, no one was larger than life. Just a realistic movie, but and and dangerous.
If they do it like that, its got a real chance.
