When Harry Met Sally...

Harry says, "I'll roll down the window," but the window alternately appears open and closed.

When driving through Chicago on the way to New York in the 1970s, a 1980s model Chevy Cavalier is visible.

When Harry, Sally, Jess, and Marie are walking down the street after their dinner, they are all dressed in coats, and Sally is even drawing herself together and raising her shoulders as if from the cold.

However, you can see trees with big, lush greenery in the background.

When Harry and Sally are in the diner and discussing whether women can fake orgasms, Sally's sandwich changes shape between shots.

The pictures that Sally drew for "Baby Talk" change during the game.

When Harry and Sally are hugging after the fight at Jess and Marie's, their arms are in one position from the front and another from the back.

The first time Harry and Sally stop at a diner (on the way from Chicago to New York), Sally opens the menu, but on the next shot, she opens it again.

Her hands are in different positions depending on the camera angle for most of the sequence.

Leaving the diner in 1977, Sally pulls the door with her right hand.

From the outside, she opens the door with her left hand.

At the final New Year's Eve party Sally's lipstick disappears and reappears between shots.

At the New Year's Eve party at end of the film when Harry is telling Sally all the things he loves about her, people in the background are still seen dancing even though the music has stopped and you hear the crowd counting down to midnight.

Near the end, when Sally is typing on her computer, apparently she is typing the longest word in the history of modern language, because her fingers never touch the "space" bar.

When Harry, Sally, Marie and Jess are at dinner during the blind date, Marie's drink often jumps from her hand to the table between shots.

When Harry and Sally are in the diner talking about whether the women have a good time in bed with him, the bite mark in Sally's sandwich keeps moving from being near the side, to the centre, and back to the side.

When Harry and Sally enter the diner in 1977, the credit card sticker on the door reads MasterCard.

At the time, the company was still known as MasterCharge and the current name was adopted only in 1979.

When Harry is dropped off in New York's Washington Square in 1977 the street signs are green and white.

In 1977 the street signs in New York were still gold and black.

When Harry and Sally are shown leaving Chicago, they are shown driving south on Lake Shore Drive from the north side of Chicago toward downtown even though the University of Chicago is on the south side of the city.

In 1977, when Harry and Sally enter the diner and also while they eat, Sally's hair is limp and untidy.

When Sally is tallying the bill, it is neat freshly styled.

When they go outdoors, her hair is untidy again.

At the very beginning of their 1977 road trip, the lock on Sally's door changes back and forth between being locked and unlocked even though she never touches it.

There were no bollards to block traffic under the Washington Square arch in 1977, as depicted in the drop off scene.

Sally tells Marie that "Harry doesn't even like sweets," but on New Year's Eve, Harry says how great Mallowmars are.

At the diner in 1977, Sally's clothing alternates between shorts and slacks as she exits the car, enters the diner, and sits down.

After Harry and Sally have sex, Sally is getting up for some water and is supposed to be naked, however as she stands to put on her robe, you can see her night gown around her legs, which must be tied up around her neck under her hair.

When Sally is faking the orgasm in Katz's Deli, the woman who says "I'll have what she's having" is seated in the self service section and a waiter would not have come over to take here order.

The waiter service section is against the wall to Sally's left.

During the scenes set in 1982 (1977 plus "5 years later") a United Airlines Boeing 737-300 is shown landing.

The 737-300 model did not start revenue service with any airline until 1984.

When Harry and Sally are in the museum, Harry makes a joke about hieroglyphics being part of an ancient comic strip.

When he says ".

About a character named Sphinxy," his lips don't match the words he can be heard saying.

When Harry and Sally meet for the second time at the airport, Sally mentions that she is twenty-six years old.

The subtitle on the next scene, in which Sally discusses her breakup with Joe a few days prior, says "Five Years Later," and Sally mentions that she is thirty-one.

In the following scene, Harry and Sally run into each other at a bookstore.

Sally tells Marie that the last time she saw Harry was six years ago, not five.

In the last scene, where Harry and Sally are seated next to each other and supposed to be "married" neither are wearing wedding rings.

When Jess and Marie are talking to Harry and Sally after they make love, a person walks back and forth in the mirror behind Harry.

The person is not a crew member but a restaurant worker as you can also see canned food on shelves.

When Harry and Sally drive from the University of Chicago to New York, they should drive on the Lake Shore Drive heading to the south (to the direction of Gary), not to the north (to the direction of downtown).

So they should not be on the Lake Shore drive on the north of downtown.

Pros:Firstly, it's definitely a classic.The chemistry between Meg Ryan and Billy Crystal on screen was superb.

This wasn't one of my favorites. I liked "Harry" and "Sally" in this movie, but yet again the story line just wasn't suiting for me.

I really like this movie. the actors are excellent highly recommend would watch it again love meg Ryan's hair and outfits billy crystal looks short i don't like her hair she should not have done plastic surgery lets make a remake everyone go and watch it.

Sally (Meg Ryan) gives Harry (Billy Crystal) a ride to New York after they both graduate from the University of Chicago. They have a spirited and cantankerous debate.

Harry Burns (Billy Crystal) meets Sally Albright (Meg Ryan) in 1977 when they need someone to share a drive with to New York after finishing college in Chicago. The film shows how, after a couple of false starts, they begin and develop a friendship, which stays constant throughout their turbulent romantic lives.

Can be a man and a woman best friends and also best lovers?

Speaking as a guy, this is one of the few "girl movies" I've ever watched. Clever, funny, well-paced, and very rewatchable.
