LOS ANGELES (AP) – “Iron Man” is showing no signs of rust.

Robert Downey Junior returns as the metallic marvel. Iron Man 3 opens with more than $175 million. That’s the second best opening ever — behind only “The Avengers” a year ago, which also featured the Marvel Comics superheroes. Worldwide the latest Iron Man has topped 680 mil.

“Pain and Gain” is a distant second this weekend — followed by “42” and “Oblivion.”
