Iron Man 2 didn't break the big Hollywood record for opening day or one-day or even 3-day weekend. "Hey, it's Iron Man, not Platinum Man," one rival studio exec quipped in an email to me. But it did launch with an "A" Cinemascore and $133.6 million, placing at least the 5th and maybe even 4th all-time best grossing weekend. That beats Shrek 3's $121.6M and possibly Pirates Of The Caribbean 3's $135.6M. But not Twilight Saga 2: New Moon's $142.8M, or Spider-Man 3's $151.1M, or The Dark Knight's $158.4M.
