Welcome back to another installment of Movie Power Rankings, where buzz means everything for Hollywood's biggest films. You probably won't be too surprised by this week's top movie. Marvel's "Iron Man 3" is already approaching the $1 billion at the global box office, and is showing no signs of slowing down (although "Star Trek Into Darkness" may have something to say about that). Robert Downey Jr. is not only renegotiating his lucrative "Iron Man" contract, but is also reportedly helping his "Avengers" team mates get a healthy pay raise for the 2015 sequel. Will that mean more green for Hulk (Mark Ruffalo) and more cash for Cap (Chris Evans)?
