Which Summer Movie Will Be the Biggest Blockbuster?

Fast Five will be the year's highest-grossing movie by the end of next weekend, but it has plenty of competition in the weeks to come, since this summer-movie season is jam-packed with sequels and expensive would-be blockbusters. So we put it to you: When all is said and done, which 2011 summer movie will be the biggest box-office hit? Pirates of the Caribbean and Transformersboth have an amazing track record, but can their latest movies come out on top in such a crowded summer? And then there's the last Harry Potter film, which is poised to score big even if last year's Potter installment was only the fifth biggest film of the year, coming in well over $100 million behind summer champ Toy Story 3 (a precedent that might bode well for Pixar's 2011 sequel, Cars 2). Give us your prediction, and don't forget about all the potential dark horses!

Nothing to do but wait for the summer (2011)

The above line is from a Leif Garrett song (remember him?), but slogging through this Christmas, and taking note of the gigantic slate of sequels and other massive movies due next year, it could sum up the Hollywood mood right now

Among the expected box-office heavy hitters for 2K11 are:

Pirates of the Caribbean 4: On stranger Tides;
The Hangover 2;
Kung Fu Panda 2
Thor

X-Men: First Class;
Cars 2
Green Lantern

Transformers 3;
Harry Potter & The Deathly Hallows Part II (series finale ?)
Captain America

looks to be an epic summer
