Continuity: Simon's cut on his lip is quite visible in the car on the trip down to Baltimore and on the way back to New York, but it miraculously disappears while they are staying in the hotel in Baltimore.

Continuity: In the hospital, Jackie goes to give Simon her mirror so he can look at himself, and her green purse is scrunched up under her arm. As the shot changes to a wider angle, the purse is now hanging over her stomach.

Continuity: In the first diner scene we see Helen dealing with some guests and she is not wearing a watch. When she passes by Melvin who is waiting impatiently for his table she suddenly has one on her wrist.

Continuity: When Simon comes to Melvin's apartment to tell him that he has found his dog and Melvin tells him not ever to knock at his door, not even when the smell of a decaying body is emanating through the door so that he has to put a hanky to his face because of the stench, the glasses he is holding in his right hand disappear and reappear between shots.

Continuity: When Melvin and Frank are talking about taking Simon to Baltimore the flowers on the table are yellow and red. When Carol is reading her note to Melvin, they're orange and purple. The colour isn't off because Carol's top looks the same as before.

Continuity: When Melvin is chasing the couple away from "his" table the flowers in the vase on the table are red and orange. When he sits down, there is now a large pink flower in there too.

Continuity: When Carol apologizes to Melvin over the phone her watch rotates around the wrist while she is holding the receiver.

Continuity: When we see Simon in hospital after being badly beaten up by the thugs, he has long, similar stitches over his face and also over the bridge of his nose. When he is released from hospital most of the cuts have left very visible scars of almost Frankensteinian quality, only the injury on the nose is hardly visible. At the end of the movie, for example when he is talking to his parents over the phone, his nose is now unblemished while the other scars still look quite frightening.

Continuity: When Melvin tells Simon in very clear terms that he doesn't wish to be disturbed for any reason whatsoever Simon's shirt is open almost down to his belt. When he turns away after Melvin has closed the door the shirt is almost buttoned up.

Continuity: After Simon does his imitation of Melvin, he apologizes to Verdell and we see him put his right hand to his forehead - and the same shot from behind him a split second later shows his hand to his mouth.

Other: Right at the end of the movie Melvin and Carol walk by a bakery. Suddenly the lights go on showing staff at work like sweeping the floor, indicating that they must have been doing this in the dark.

Continuity: When Melvin feeds Verdell for the first time the dog is standing still at the edge of the carpet, facing his dish. When the camera angle changes he is standing further back. Then he lies down, and when the camera angle changes again he is lying at a different spot.

Continuity: When Carol brings her date home he lifts her up, puts her on the sofa and starts kissing her down the right side of her neck. When the camera angle changes he is kissing her on her mouth with his head on the other side.

Continuity: In the beginning of the movie, when Simon asks Melvin if he has seen his dog, he has a towel thrown over his shoulder which is differently arranged in shots from the front and from the back.

Continuity: When we see Melvin's bedroom, when Simon is looking for the dog, the shelf above his bed is half filled with books and bottles of water. By the end of the phonecall with Carol, the shelf is completely filled.

Continuity: When Melvin and Carol are talking in the restaurant about Spence's asthma, the plates that Carol is holding are rotated differently in each shot. Also the way she is holding them keeps changing (hand under the plate or thumb over the rim).

Continuity: When Simon is explaining to the model how he decides how to paint a person and then tells him to hold it, we see the position the model is in. However, in the very next shot his hand is in a different position it was than when he told him to freeze it.

Continuity: When Jack Nicholson answers the door when Helen Hunt comes over in the rain, his hair is standing up crazily. In the very next shot, it is neatly pressed down - he didn't have time to run his hands through his hair to fix it between shots.

Continuity: In the scene before she goes to Melvin's house, she is sitting on the couch wide awake. Helen hunt Has one blue eye and one brown.
