The New ‘Iron Man 2’ Trailer’s 10 Most Important Scenes

“It’s good to be back,” says Robert Downey Jr. as Tony Stark makes his grand entrance in the new “Iron Man 2” trailer. And indeed it is, because the new trailer offers fans even more cool footage from director Jon Favreau’s upcoming sequel to the 2008 blockbuster.

While there’s a lot to like about the new “Iron Man 2” trailer, there are a few key scenes worth a closer look. You can check out a gallery of images from the trailer here on MTV.com, but here are the 10 scenes you might want to check out again — and some thoughts (and questions) about what they could mean for Tony Stark’s return to the big screen.

0:25 — Tony gets his first glimpse of Natasha Romanoff (Scarlett Johansson) in this scene, and she’s introduced as a notary. Tony responds as expected (“I want one,” he says), but we can’t help wondering whether this notary will side with the good guys or the bad guys once she becomes Black Widow.

1:19 — Um, what’s Tony Stark up to in this scene? “Contrary to popular belief, I know exactly what I’m doing,” says Stark. Well, that makes one of us — but with that crazy laser messing up his workshop, we’d sure like to know.

1:27 — Wondering where all those robot drones we saw in the last “Iron Man 2” trailer came from? Well, after seeing Ivan Vanko (Mickey Rourke) join Justin Hammer (Sam Rockwell) for a meeting, it looks like we have our answer. “You need my resources,” Hammer tells him. “I want to make Iron Man look like an antique.”

1:40 — A nice debut for War Machine, but did you notice all those robot drones behind him?

1:44 — Yes, this scene is awesome. However, it’s worth noting that the drone in the forefront of the scene has “Navy” on his shoulder. What could put War Machine against a host of government-sanctioned drones?

2:02 — Who’s in the Mark II armor? We know James “Rhodey” Rhodes becomes War Machine, but there’s any number of other characters who might have an opportunity to get into the ring and go armor-to-armor with Stark.

2:04 — Cue cameo by Samuel L. Jackson as Nick Fury. Now that we know “Iron Man 2” takes place before “Incredible Hulk” in the Marvel movie timeline, where does this scene fit?

2:11 — Well, I guess we know how Tony Stark survives that Monaco Grand Prix encounter with Whiplash… but what’s that armor he’s wearing?

Wait for it…

2:13 — It looks like Natasha Romanoff is a little more than a notary in this scene. How does she get her hands on Iron Man’s gauntlet? Could she be the one in the Mark II armor we saw a few scenes back?

2:21 — Hey, remember that strange new armor we saw in the Monaco scene? Well, it’s so cool it deserved three images. Behold, the BRIEFCASE ARMOR!
