THE HOBBIT: THE DESOLATION OF SMAUG

The first great sequence in The Hobbit: The Desolation of Smaug - and, sadly, one of the few truly great sequences in Peter Jackson's second (or fifth, if you'd rather) J.R.R. Tolkien installment - is an escape scene. At its start, hobbit protagonist Bilbo Baggins (Martin Freeman) and his dwarf companions sneak out of the Elven dungeon cells in which they've been imprisoned, and hope for clean getaways by stashing themselves in empty wine barrels and floating down a nearby river. Sounds simple. And it might have been if it weren't for the rapids, and the waterfalls, and the whizzing arrows, and the savage orcs, and Orlando Bloom gingerly bouncing atop our heroes' heads.

PIRATES OF THE CARIBBEAN: ON STRANGER TIDES

During the first hour of Pirates of the Caribbean: On Stranger Tides, the third sequel in Disney's hugely successful franchise, characters are routinely told to beware of the mermaids - half-woman/half-fish beings who use their comely looks and tranquil siren songs to drag seafaring men to their deaths. Our adventurers take note of the warnings but pay them little mind, and really, why should they? Disney, after all, is the studio that gave us the benign cutie-pies of The Little Mermaid and (through its Touchstone Pictures label) Splash. Just how nasty can these things be?

We eventually find out, and as a result, I'll likely never look at Ariel or Daryl Hannah the same way again.
