I found some of these really funny.
"If you watch Raging Bull backwards, it's about a fat comedian who becomes a boxing champion and the more he beats his wife and brother, the more they like him."
"If you watch The Big Lebowski backwards, The Dude finally gets his rug back."
"If you watch The Shining backwards, it's about a murderer who is convinced by ghosts to give up the drink and settle down for a nice vacation with his family."
"If you watch 300 backwards, King Leonidas helps the messenger out of the well with his foot and tells him 'SPARTA IS THIS!'"
"If you watch Thelma And Louise backwards, it's about two women with a flying car who slowly realise their place is in the kitchen."

If you watch Titanic backwards it's about a bunch of Polar Bear Club members who build a giant ship in the ocean and sail it to New York.
