Movies similar to Iron Man 3 open to an average $87.72 million. The first Iron Man opened to $98.62 million while the second opened to $128.12 million. The Marvel franchise has an established fan base, and this movie’s going to have one of the best opening weekends ever. The popularity of The Avengers has helped gain the Iron Man movies more fans, and this is the first Avenger-member super hero movie since the release of The Avengers, this same weekend last year. While this doesn’t stand much of a chance at matching The Avengers‘ record-shattering $207, 438, 708 opening, nor am I imagining it topping the number two opening weekend record of $169, 189, 427 held down by the eighth Harry Potter movie. Though, because of the franchise’s increased fan base thanks to The Avengers, and the fact that the excellent Ben Kingsley might attract older audiences, I can really visualize this topping The Dark Knight Rises‘ $160, 887, 295 (the third opening weekend all-time record) and finishing the weekend with $166, 016, 000.
Here’s how I see the top 10:
1. Iron Man 3: $166, 016, 000
2. Pain & Gain: $9, 595, 900
3. Oblivion: $8, 259, 800
4. 42: $6, 219, 950
5. The Croods: $4, 670, 500
6. The Big Wedding: $4, 360, 210
7. Mud: $2, 300, 000
8. G.I. Joe: Retaliation: $2, 200, 000
9. Scary Movie 5: 1, 770, 305
10. Olympus Has Fallen: $1, 740, 000

Dude. I think you are THIS CLOSE to getting the exact number for Iron Man. Early reports say it brought it $65-68 Million on opening day.
Hahah, well I’ll be happy if I’m within $10 million for my first summer movie prediction 😀
I think Iron Man 3 will get more than that, not sure though. Good luck 😀
The estimates are in, it’s made $175.3M this weekend! I’m within $10 million, so I’m quite content lol 😀
That was 80% my good luck 😀
Hahah, sure, sure! Hopefully the actual number’s a bit lower so I can be closer lol 😀
