This. Although Avengers will cut it VERY close.I love the other two, but Batman wins for several reasons:
1) Its an established film franchise. Spiderman is a reboot and this is the first Avenger film.
2) We don't know how good the other two will be.
3) Christopher Nolan always delivers and if anyone can break the third-act curse, its him.
4) Its Nolan's last Batman film.
5) It will be riding off the success of The Dark Knight. Remember how popular Spiderman 3 was after Spiderman 2's success? Yeah its gonna make that look microscopic.
Hulk
Iron Man
Thor
Captain America
Avengers will redefine the team superhero movie. 4 franchises coming together after 10 years of hype? Plus Whedonites?
Avengers will own all the competition.
This. Although Avengers will cut it VERY close.
EDIT: Actually, Spidey will be in 3D so you never know... I think it'll be very close but Batman 3 will win it.
MARVEL
Because DC/WB is still twddiling their thumbs and the (Batman) fans are a bunch of elitists
If IM2 does as well as the first, that's one helluva start.
IM2 will make $425+ million domestic and probably $800+ million worldwide. It's going to be a huge hit. The first one had very strong word of mouth and the sequel is set to explode like recent sequels in the Pirates, Batman, and Transformers franchises.
If it's that big, then the Avengers will have a huge leg up on Batman and Spider-man. Avengers would be like an Iron Man sequel, so it has some serious box office momentum going for it. How Thor and Cap does will probably determine if it beats Batman and Spidey.
Are we talking box office here?
Avengers does have potential to beat Batman though. It depends on how IM, Cap, and Thor does. If IM2 does as well as the first, that's one helluva start. If Cap and Thor are successes as well, it could be a real contender to win the summer. It's easy to see how everyone will flock to see the Avengers based on name recognition, but throw in three success movies setting it up and you have a huge blockbuster on your hands.
Why would that be a huge leg up on Batman?
add Superman reboot in Christmas 2012
2012 isnt the end of the world...its the biggest box office year ever.
Let's not forget, whilst we all certainly hope that Captain America and Thor are great and successful movies, that is not guarenteed. The Avengers could be coming on the back of one or two flops, or medium-sized hits ala Hulk and Superman Returns, and thus lose momentum. Whereas the last Batman and Spider-Man movies are two of the most succesful movies of all time.
I really don't care, all I know is it's going to be one helluva year
