Do You Really Want to Know How It Ends?

The Ending - Teddy Gammell did not kill Leonard's wife.  Teddy was the police officer in charge of the break-in case who ended up helping Leonard track down and kill the second intruder.  When Teddy finds out that Leonard killed Jimmy because Leonard thought Jimmy was the second mugger, Teddy reminds Leonard of what really happened after the night Leonard lost his ability to retain short-term memories.  Leonard's wife actually survived the attack.  The story about Sammy and his wife was really what happened to Leonard.  In fact, Sammy never had a wife.  It was Leonard's wife who died of the insulin overdose while testing Leonard's short-term memory.  Teddy has been using Leonard to kill drug dealers while Teddy steals the money, figuring that a guy who can't remember anything would be able to live with what he's done.  Leonard refuses to accept everything that Teddy tells him, so he makes a note to himself that that Teddy's license plate is that of his wife's "killer."  He then notes on the back of Teddy's picture that Leonard should not believe his lies, even though at this point he knows that Teddy is telling the truth.  Thus at the start of the movie, Leonard kills Teddy for killing Leonard's wife.

The Ending - Laura Vasquez is the Light of Zartha and the daughter of a Zarthan princess that Kay fell in love with, although she has no idea what Kay's talking about.  Jay and Kay, with the help of Frank the Pug, rescue everyone at MIB headquarters.  The agents then race against the clock - and Serleena - to send Laura back to Zartha before she accidentally destroys the planet.  The agents kill Serleena and Laura is safely returned to her home planet.  The torch on the Statue of Liberty is actually a neuralizer and flashes in order to remove the memory of what happened from the entire city's population.

The Ending - John Anderton is innocent of the murders of Leo Cross and Agent Danny Witwer.  Anderton was set up by his boss, Lamar Burgess, because he discovered a flaw in the system - the Pre-Cogs don't always agree on the future crimes.  Whenever these differences occur, the minority report is deleted from the system, but not from Agatha's memory.  Anderton is finally captured and placed in stasis until he's freed by his wife.  During a reception for the nationalization of the PreCrime program, Agatha's visions of her mother's murder are displayed for everyone to see - that Lamar killed her mother and had used the system to get away the murder.  The PreCrime program is permanently shut down.

The Ending - John Klein discovers that Indrid Cold, the Mothman, only appears before major catastrophes.  Klein returns to Point Pleasant, WV, but doesn't tell Connie what he learned in Chicago.  Klein receives a call from Gordon Smallwood telling him that the Mothman is right, then hangs up.  Klein heads to Gordon's house and finds Gordon dead beside a tree, the result of freezing to death eight hours earlier.  Klein tells Connie that he spoke to Gordon on the phone no more than an hour earlier.  Cold warns Klein about a disaster on the Ohio River, but Klein mistakes the event for something at a chemical plant.  He tries to warn the governor, who's speaking at the plant that day, but comes across as being crazy.  Klein watches the governor's speech, but nothing happens at the plant.  His waitress hands him a letter that was left for him, apparently sent by Indrid Cold telling Klein that his dead wife will be calling at his house in Georgetown.  Klein leaves Point Pleasant and returns home.  Connie calls him and asks that he ignore Cold's offer to speak to Mary and return to Point Pleasant.  Klein gets the call from his dead wife, but doesn't answer it.  He returns to Point Pleasant just in time to see a traffic jam on a bridge over the Ohio River.  The bridge collapses, killing 36 people.  Klein saves Connie from drowning and becoming number 37.  Klein and Connie recall Connie's dream where she was drowning, with presents all around her, and a voice saying "Wake up, number 37" (Klein was the one who said "wake up" when he rescued her from her car).  Nobody from Point Pleasant reports seeing the Mothman again after the bridge collapse.

The Ending - Babe (or Pam as Mr. Deeds knows her) is filming everything she does with Deeds, but her tabloid TV show Inside Access edits all the footage to make Deeds seem like a bad guy.  Deeds breaks up with Babe and sells his shares of the company to Cecil.  Cecil announces at the Blake Media shareholder's meeting that he's firing everyone and selling off the company.  Babe appears with Blake's personal diary and announces that Deeds was not the rightful heir to the company.  Emilio, Blake's longtime butler, was actually Blake's illegitimate son.  Emilio fires Cecil, keeps the company intact, and gives Deeds $1 billion as Deeds returns to Mandrake Falls with Babe.  Deeds finally gets a card published by Hallmark.  Deeds buys everyone in town a red Corvette.
