Robert Downey Jr. made a surprise entrance at the Iron Man 3 panel at SDCC this weekend. You can see it below. Downey Jr. basically runs through Hall H dancing and showing off his Iron Man glove, which is awesome. He really seems to enjoy playing Tony Stark/Iron Man, and who can blame him? It’s rejuvenated his career and made him gobs of money. Personally I hope he keeps playing the character for a long time.
