ReelzChannel: Top 10 "Wow, You've Really Let Yourself Go" Movies

In the brand new Shrek Forever After, an ill-advised pact with a conniving Rumpelstiltskin (Walt Dohrn) turns reality upside-down for everyone's favorite Scottish-accented ogre (Mike Myers). Princess Fiona (Cameron Diaz) no longer loves him, Donkey (Eddie Murphy) is downright terrified of him (and still annoying), and everyone in the kingdom of Far Far Away wants his head on a pike.

When fantasy's ultimate swashbuckler can no longer buckle his swash, you know things are bad. (We can think of two reasons for so bloated a feline; for the sake of propriety, we'll go with an overindulgence in Tender Vittles.)

Puss isn't the first to have his downhill slide observed by the merciless eye of the camera. In fact, the list of characters who've undergone unfortunate cinematic transformations is considerable. Take a look at these 10 particularly distressing cases, and see if it doesn't inspire you to reactivate your New Year's resolutions.
