That’s the big question. Will ‘Indiana Jones and the Kingdom of the Crystal Skull’ do an ‘Iron Man’ or ‘Prince Caspian’ weekend. The last one, ‘The Chronicles of Narnia: Prince Caspian,’ had much lower opening than what initial tracking indicated. ‘Iron Man’ however, surprised the industry by breaking $100 million in the US during the first couple of days.

Tracking numbers for ‘Indiana Jones 4′ are good, but will it be able to top the opening of ‘Spider-man 3′ last year? The comic book hero made over $151 million in its first weekend, beating the $136 million opening by ‘Pirates of the Caribbean: Dead Man’s Chest’ in 2006.

The first two ‘Indiana Jones’ movies didn’t even cross the $200 million bar domestically during their total running time. But the first ‘Indiana Jones’ only cost $28 million and the second $48 million. The new ‘Indiana Jones’ movie is rumored to cost anywhere between $125 and $200 million to produce. Including marketing and distribution, the movie has to make $400 million before Harrison, Spielberg and Lucas will get paid.

Although you can view the daily box office in the left sidebar since today, we didn’t want to miss out on the weekend graph. What happened? In short, ‘The Chronicles of Narnia: Prince Caspian’ disappointed. The industry was expecting it at least to beat its prequel, which made $65.5 in its opening weekend. Some even said it would do $80 million. But as it turns out, people weren’t that crazy about Caspian, since it only made $57 million. Not bad, but with its budget rumored to be between $100 and $200 million, its opening weekend could have been a tad higher.

If it wasn’t for ‘Speed Racer,’ ‘Prince Caspian’ might have made some ‘loser headlines.’ But as we can see in the graph above, Narnia is doing amazing compared to ‘Speed Racer.’ The flashy movie didn’t even manage to top $30 million in the US after two weekend. Now it’s the question if people will remember the Wachowski brothers for ‘The Matrix’ or ‘Speed Racer.’ Can the success of one make up for the failure of the other?

‘Iron Man’ and ‘What Happens in Vegas’ both had another good weekend, with respectively $31.2 and $13.9 million. ‘What Happens in Vegas’ has already topped $40 million in the US, $5 million more than its budget.
