‘Iron Man’ retains its iron grip

First the bad news: “Iron Man” dropped 48 percent over its opening weekend.

Now the good news: That means the film still made a whopping $51 million, making tin foil out of its competition – the lame Ashton Kutcher/Cameron Diaz comedy “What Happens in Vegas” and the Wachowski brothers’ version of a kid’s flick “Speed Racer.”

We’ll see how well “The Chronicles of Narnia: Prince Caspian” fares when it opens in 3,800 venues on Friday.

For me, I’d see “Iron Man” five times rather than be forced to watch another “Narnia” movie a single time.
