It's a sad but true fact that movie studios didn't have much faith in Deadpool, and if Ryan Reynolds hadn't championed the picture it may not have made it to the big screen.
But now I bet the studio is wishing their box office projections had been a bit more accurate, because they could have left in all kinds of cool stuff that ended up on the cutting room floor.
io9 put together a comprehensive collection of Everything That Was Too Expensive To Include In Deadpool, and in the interest of remaining spoiler free here's a partial list of what was cut:
a bartender, a guy with robot arms, a young member of the X-Men, a couple of villains, a couple of heroes and lots of sweet action scenes. 'Nuff said!
