I dont know why people keep suggesting The Invincible Iron Man. Sure, it's a good title, but have they already fogotten http://en.wikipedia.org/wiki/The_Invincible_Iron_Man ?
On the other hand, it wasn't very good, so I can see why people would forget it.
Seriously, Iron Man 2 is fine.
I2: MACHINES UNITED
(because.. u know... mr war machine is here...)
Since this is the studio flagship howsabout they do a 'Star Wars' type of Title. Iron Man for the first picture, then maybe just 'Armor Wars' for the second movie...although 'wars' might be over the top. 'Stark Enterprises'
Minimalizing Iron Man to just initials just don't schwing w/ me..."hey man I can't wait for that EYE EMM Deuce/2" ....Ahole
Tha'd be like the next Batman film to be titled B7
As long as Tom Cruise stays 50 feet away then I'm sure the public won't be confusedI think IM:II is just fine.
IIron Man
How about calling it......Iron Man:No Lame Action This Time
Iron Man II: Revenge of a Terminators Salvation conflicted with Angels and Demons with many Star's to be Trekked.
