Oh, Tony, you just invite trouble right through the front door, don't you? Well, actually, that's exactly what he does in this first clip from Iron Man 3. Like, he literally invites Mandarin to his home and promises to leave the door unlocked. Now, that might sound all chummy and full of hospitality, but if you watch the clip you'll see Stark's not exactly inviting the super villain to a tea party.
I don't think there's much debate around the fact that, as a personality, Robert Downey Jr's Tony Stark is probably the most important character in the Marvel universe right now. He's just so charming! But I'll be damned if he doesn't know when to shut the hell up, because if the trailer is any indication, Mandarin does come a knockin'. Hard.
