Visible crew/equipment: Towards the end of the movie when Whitney Houston is in her hotel room with Kevin Costner you can see the mic in a reflection in the window of the suite.

Plot hole: It doesn't make any sense that Portman places a bomb in the boat as his only target Rachel was the least likely to take a round on the wintry lake.

Other: It's not really a mistake but when Rachel is our running and she asks Frank to walk with her, if you look in the background, there are 2 "ghosts" walking hand in hand behind them.

Continuity: When Frank's dad is cutting mushrooms while cooking dinner, he slices a mushroom in a closeup. In the next shot, the mushroom is whole again.

Continuity: When Frank impresses Delaney with his knife-throwing skills he starts with some antics which even endanger Delaney. Delaney tries to get out of the way and waits next to a big garden bowl. When Frank asks him not to stand there either the bowl is gone.

Continuity: In the scene in Frank's basement the ends of Rachel's scarf change: Before she picks up the sword the right end is longer, afterwards the left end. In between there's a close-up where she is holding the sword in front of her and where both ends are at level.

Continuity: In the scene at the Miami hotel, when Rachel and Portman are in her bedroom, someone gives Frank a fresh drink of orange juice. He takes a deep sip, the camera cuts to Rachel's bedroom door, and when it cuts back to Frank the glass is even fuller than when he got it.

Continuity: In the scene where Frank puts Rachel to bed. He moves some dolls aside by pushing them, and the dolls fall over. In the following shot, where Rachel is in bed, one of the dolls is sat up straight.

Continuity: When Frank comes to Rachel's house for the first time he talks into a rather decrepit intercom with some bent wires hanging out. In one shot, when he says "This is Alexander Graham Bell to see Miss Marron", the wires are hanging straight.

Continuity: In the scene where Rachel stops her jogging and asks Frank for a date she has her natural skin color. In the last shot of the scene, when she leaves, her face has the almost Michael Jacksonian off-white make-up which is more typical for the rest of the movie.

Continuity: The bar scene of Rachel's and Frank's date contains a lot of editing flaws: 1) Rachels position switches between both arms down and chin rested in hand, 2) in one shot from the back we see her lifting her glass to her mouth, but when the camera angle changes she's not drinking, 3) the way Frank holds his glass switches between full hand and thumb plus two fingers, 4) Rachel's bangs change between straggly and fluffy.

Continuity: When Frank makes a control round through the Miami hotel kitchen he beats up a creepy but nevertheless innocent guy. When he is done the collar of his jacket which had been neatly folded down throughout the manhandling suddenly stands up.

Continuity: In the evening following Nicki's funeral Frank and Fletcher have a talk. Fletcher's arm switches back and forth between lying on Frank's backrest and hanging down.

Continuity: At the Academy Awards scene, when Frank shoots Portman the second time, Portman receives an (entry or exit) wound on his temple. However, the way he was standing after being shot in the chest the bullet could only have hit him from the front.

Continuity: In the first shot in the dressing room of the Mayan there are some white and some pink flowers on the table in front of the mirror. In the next shot the pink flowers are gone.

Continuity: When Tony attacks Frank in the kitchen Frank is eating an apple. We see him cutting off and eating two slices, but in a close-up of the apple only one small slice is gone.

Visible crew/equipment: When Frank comes back to the hotel room after the beating in the hotel kitchen Delaney informs him that Rachel had received another call from the stalker. In the scene there is a reflection of the mike in the window, and we even see how it's turned around when the take is over.

Continuity: Right after Frank gets shot he shoots Portman and you see someone helping Frank get his jacket off as he's lying on the ground. The camera angle changes and you see his jacket back on and someone is starting to help him take it off again.

Factual error: When Whitney Houston turns up at the Oscars, it's night time. In reality, guests to the Academy Awards always arrive in the afternoon.

Continuity: After Frank has moved into Rachel's garden house he comes to check Nicki's apartment. When he looks at a wall with some photographs there's a close-up of an old picture of Rachel and Nicki performing. In the close-up there is a pattern of light and shadows on the wall which was not only not there in the previous wide shot but which is also only visible on the wall and not on the photograph.
