Giant robots kicked some shiny metal butt last weekend as the new Transformers movie earned the second highest gross of any film in its first five days (The Dark Knight still has the lead). In the wake of all this cybernetic mayhem, My Sister's Keeper did respectably well enough to take fifth on its opening weekend. Here's the top five:

1. Transformers: Revenge of the Fallen: $108.9 million ($200 million since Wednesday)
2. The Proposal: $18.6 million
3. The Hangover: $17 million
4. Up: $13 million
5. My Sister's Keeper: $12.4 million

Two new releases this week, each with a historical flair.

Ice Age: Dawn of the Dinosaurs
What's It All About: This is the third installment in the popular animated series. This time around our gang of prehistoric pals discover an underground world in which dinosaurs still exist.
Why It Might Do Well: 2006's Ice Age: The Meltdown had a $68 million dollar opening weekend.
Why It Might Not Do Well: Rottentomatoes.com is giving it a disappointing 37%.
Number of Theaters: 3,993
Prediction: $66 million

Public Enemies
What's It All About: Michael Mann directs this film about depression-era bank robber John Dillinger.
Why It Might Do Well: Johnny Depp, Christian Bale and Academy Award winner Marion Cotillard make for a compelling cast, and based on the trailer they pull off the period setting quite believably.
Why It Might Not Do Well: Only 57% at Rottentomatoes.com.
Number of Theaters: 3,200
Prediction: $28 million

I think next week's top five will look a little like this:
1. Ice Age: Dawn of the Dinosaurs
2. Transformers: Revenge of the Fallen
3. Public Enemies
4. The Proposal
5. The Hangover
