According to early estimates from Box Office Mojo, this summer's second big-budgeted extravaganza failed to pick up more than $20 million at the box office this weekend, with the poorly-reviewed comedy What Happens in Vegas finishing right behind in third. Of course, Iron Man took the top spot for a second week in a row with roughly $50 million, while Speed Racer -- which some projected to take home at least $30-40 million -- came in second with $20.2 million, as What Happens in Vegas slid into third with $20 million. Rounding out the top five were Made of Honor ($7.6 million) and Baby Mama ($5.7 million).

So what happened to Speed Racer? Part of the reason had to do with its targeted audience, which, supposedly, was kids, though kids weren't very familiar with the cartoon the film was based on. That, and the flick clocked in at over two hours -- a running time that's been mentioned a lot this weekend, as well as one that's way too long for a PG-rated kiddie adventure. That said, its PG-rating scared away those adults who grew up with the cartoon; people who, most likely, were looking for something a bit more skewed toward adults (especially when Iron Man came out the weekend before and kicked a whole lot of ass). Nevertheless, I'm pretty sure we can rule out that Speed Racer franchise at this point.

Coupla questions for ya: Why do you think Speed Racer failed to power across the finish line in spectacular fashion? Also, what happens to the Wachowski Brothers now? Will folks think twice before giving them $150 million and free reign?
