Saturday Box Office: Iron Man Targets $52M Second Weekend; Speed Racer Heads For Disappointing $18.7M Opening

The Saturday Box Office estimates are in over at Fantasy Moguls, and Paramount's Iron Man is beating it's second weekend expectations, adding an estimated $21.72M on Saturday, which should result in a $52M 3-day ($163.66M cume). Speed Racer is doing even worse than expected, heading for a very disappointing $18.72M opening weekend. Surprisingly, this should be just enough to Fox's What Happens in Vegas, which is expected to end short with $17.6M.
