Robert Downey Jr. is back as the hip, fast-talking Tony Stark in Iron Man 3 ($35 for the 3D Blu-ray set), and this time he faces an enemy known simply as The Mandarin, whose origin may or may not involve being raised in a radioactive Mandarin orange grove. Either way Iron Man is clearly gonna be up for a little orange crush, as his main squeeze Pepper Potts (Gwyenth Paltrow) tries to keep Stark from falling into a pit of despair. Does Iron Man still have the juice? (I hate myself.)
