After holding on to the top spot at the box office for two consecutive weeks, Iron Man has been dethroned by Prince Caspian, the second film in the Chronicles of Narnia series. Prince Caspian opened with a $56.6 million weekend gross, which was about $9 million less than its predecessor, The Lion, the Witch, and the Wardrobe did in 2005. Iron Man dropped to second with $31.2 million in ticket sales, and has now grossed $222 million in just three weeks.

The only other new entry in the Top 10 list was the indie film The Visitor, which earned $687k. That should be enough to buy the writer/director a new house — or at least some new furniture and a mattress topper or two. I don’t think I’ve ever seen a movie crack the top 10 with just a six-figure weekend, but I guess I could be mistaken. This is actually the fifth week of The Visitor’s theater run, but it has just broken into the Top 10 now.

At any rate, here’s the complete list for the weekend ending 5/18/08 — and remember, Indiana Jones opens next week!

  1. The Chronicles of Narnia: Prince Caspian, $56.6 million
  2. Iron Man, $31.2 million
  3. What Happens in Vegas…, $13.8 million
  4. Speed Racer, $7.64 million
  5. Baby Mama, $4.59 million
  6. Made of Honor, $4.5 million
  7. Forgetting Sarah Marshall, $2.54 million
  8. Harold & Kumar Escape from Guantanamo Bay, $1.8 million
  9. The Forbidden Kingdom, $1 million
  10. The Visitor, $687k
