What Happens in Vegas

At the retreat you can clearly see the drummer not making contact with the snare drum.

His brush is in mid-air.

At the retreat, when Joy slaps the "Hello my name is Joy's Bitch" sticker on Chong's back, you can see it shift places and angles from shot to shot.

The position of Joy's hair changes when she quits her job.

In the scene where Jack and Joy first tell each other why they're in Vegas, the ice in Joy's drink refills and empties depending on the camera angle.

The slot machine the progressive jackpot is won on shows that 2 coins are needed to win the jackpot.

Jack deposited only 1 coin.

Joy throws dice that are opaque.

Opaque dice are never used in casinos.

When Joy goes to work the day after moving in with Jack she is wearing a blue dress.

When her boss tells her one of the ladies will be promoted she is wearing the gray dress she had on in the opening scene.

when she returns home she is in the blue dress again.

At the end of the movie when the main characters are on the beach, the height of the sun and the time of day changes drastically.

When Jack and Hater try to see who finishes the beer first Hater's is gone and Jack has a little left.

When they show Jack's glass again it is almost full.

Joy leaves for work with her smoothie, but the smoothie is gone when she gets onto the sidewalk after climbing the subway stairs exit.

The scene where Joy is bombarded with files on her desk before the scene where Jack is punched, appears again when she is talking to her boss about the birthday party she went to, with her wearing the same outfit.

At the end of the movie, Jack is seen crossing the Robert Moses Causeway and Captree Bridges from Long Island to Fire Island, but in the next scene it shows him crossing the ferry from the mainland to Fire Island.

When Joy is disinfecting Jack's bed, the bedding is solid blue.

When we last cut to her, the top sheet is red striped.

The logos on the basketball Jack holds move around as his father confronts him at the shop.

When Joy shows the marriage counselor a video of Jack and his two friends fighting outside her apartment with her cell phone, you can clearly hear their voices, but in reality there was no way to record their voices from her window.

When Joy and Tipper arrive to the hotel room, they laid on the bed and unmade it.

When Jack and Hater arrive, the bed is made.

In one scene, Jack is wearing a gray t-shirt.

When the camera is in front of him, his sleeve is rolled up, when the camera is behind him, his sleeve is rolled down.

When they are playing the slot machine talking, it actually would have paid a small amount with the jackpot symbol-jackpot symbol-seven before they actually put the borrowed quarter in and hit the jackpot.

After Jack's father makes the last shot to win their basketball match, the ball can be seen swishing through the hoop and bounce a couple of times, on the next wide angle shot showing his father walking away, the basketball is no where to be seen.

The initial shot of the Las Vegas "strip" shown just after both sets of characters leave New York was printed optically reversed; the casinos are on the wrong sides of Las Vegas Boulevard S and the signs for Bellagio and MGM Grand and the on-building sign for Monte Carlo can all clearly be seen to be mirror-images.

Joy is so wasted, she doesn't realized what happened until the morning after, yet later berates Jack for buying her wedding ring out of a vending machine.

However, the if the ring was plastic or fake is was probably very obvious that it was bought from a vending machine, or she used the term in mockery, which isn't uncommon.

In the scene where Joy and Jack race to the counselor's office, Joy's hair clearly changes from just a hot mess to a hot mess looking afro.

When Jack rolls a 7 at the craps table during the retreat, the dealer pays off a number of field bets.

A 7 is a losing roll on a field bet.

Hater tells Jack that a Las Vegas marriage can only be annulled or dissolved in the state in which the parties reside.

As evidenced by the fact that Louisiana resident 'Britney Spears' (qv)'s first marriage was annulled in Las Vegas, where it took place, Hater is wrong.

However, he is a pretty lame lawyer so this is not necessarily a goof.

- PLOTJack, Joy, Hater, and Tipper were all drunk enough not to remember what happened the previous night, yet they don't have hangovers.
