Yep, with the summer movie season officially underway, 'Pirates of the Caribbean: On Stranger Tides,' the fourth installment in the popular Disney franchise, is this weekend's only major new release, opening in 4,000 theaters nationwide on Friday.

One has the makings of a mega-blockbuster in 'Thor,' the latest in a long line of superhero movies from Marvel. Interestingly enough, this one is from critically acclaimed and Oscar-nominated director Kenneth Branagh, the man behind such Shakespeare adaptations as 'Henry V.'

The other big releases this weekend are a nice alternative to the loud thunderous action in 'Thor.' The first is 'Something Borrowed,' based on the popular book by Emily Giffin, starring Kate Hudson and Ginnifer Goodwin. If that doesn't float you boat, you may want to try 'Jumping the Broom,' about two very different families who come together for a wedding at Martha's Vineyard.
