Plot hole: In the scene where Ashley Judd runs away from her attacker and falls into her aquarium he has moved to the bottom of the stairs - there is no way he would have been able to move that full fish tank. It looked to be about a 30 gallon tank - it would weigh about 400 pounds with the stand and even if he slid it with some superhuman strength, glass tanks are notorious for shattering when you move them full. Plus it would've made enough noise to wake the dead - no way she wouldn't have heard it.
Continuity mistake: Morgan Freeman falls in a water hole while chasing the bad guy. In the next scene his shirt is completely dry again.
Continuity mistake: Ashley Judd has just handcuffed the bad guy to the stove, Morgan Freeman walks in and has the little talk with the bad guy why not to light the lighter and blow up the room. Just when Morgan Freeman shoots the bad guy in the head, the bad guy flies back with BOTH arms visibly flying backwards. In the next shot with the bad guy dead, his hand is once again handcuffed to the stove. (01:50:30)
Continuity mistake: When Ashley Judd is working on the 8 year old girl thrown from the motorcycle she is wearing goggles. They go from over the skull cap to underneath it in different shots.
Other mistake: When Ashley Judd is being chased by the killer she runs downstairs and hits her aquarium. In the first shot you see her turn her back and hit the aquarium, in the next shot you see her hit it with her shoulder.
Continuity mistake: While chasing the bad guy, Morgan Freeman falls through a water hole, droping his gun. In the next scene he climbs out of the hole with his gun in its holster.
Continuity mistake: When Kate is making airline reservations for her and Alex back to North Carolina, and Alex tells her to hang the phone up, Kate's hand disappears from the receiver between shots. (01:15:15)
Continuity mistake: Cross enters the interrogation room, with Dr. Sachs detained. He's carrying a cup of coffee and a file. He puts the coffee on the table, and in the next shot you can see already on the table the file that he never put down and is in fact still in his possession in the shot that follows. (01:21:05)
Other mistake: In the Italian dub, Dr. McTiernan talks to the two Chinese women with both of them speaking the language, making the dialogue quite paradoxical (since the point of the scene is that the older woman speaks only Chinese and the other has to act as translator). Not just that, but she introduces herself as Dr. "McTiernenson", for the one and only time in the movie. (00:21:10)
Continuity mistake: Cross is tired of waiting and pushes through the doors marked Main Offices. He advances through the open space; a policeman on the left of the frame is passing a file to a colleague sitting at her desk. Close-up of Morgan Freeman holding his badge, and the same policeman is repeating the gesture, arriving and handing over the file. (00:12:25)
Continuity mistake: Once Cross comes back home from the intro, he finds relatives there. Next to the mother there's another person (Cross' daughter, Janelle). She conveniently disappears between shots though, so Cross can sit next to May. She would have had to quickly backflip over the couch or slide on the floor to exit stage off-camera. (00:08:40)
Revealing mistake: In the locker of the Gentleman Caller there are multiple newspaper clippings. When Cross looks at the one talking about his niece, it just does not talk about his niece. The clipping is on camera long enough to be able to read without freeze frame, and it's talking about things like police brutality and apartheid (actual word used), entirely unrelated to the fake headline and picture caption. (01:18:00)
Audio problem: Hotel room scene; after assessing the state of a shirtless Cross' ribs, Kate says "At least now the FBI know who they are looking for." Most of the sentence is pronounced off-screen, but it begins with Ashley Judd with her mouth shut. (01:14:35)
Continuity mistake: Watching the two guys spar in the gym, Kate in one shot (when the red shirt guy is finishing his punch combo and backs off to load the kick) is leaning on the railing, arms crossed. In every other shot she is standing, hand on her hip. (00:22:00)
Continuity mistake: When Cross and the lewd red herring doctor talk about the imaginary Futokan bottled water, Morgan Freeman has his left hand on his right wrist when he is shot from the side, but he has his hands joined when the camera is behind him. (01:21:50)
Continuity mistake: Cross is talking to Kate who woke up from her drug-induced coma. He mentions his niece and she says "I talked to her." In this part of the scene, Cross' hand goes on and off her shoulder depending on the camera angle. (00:53:00)
Continuity mistake: Cross shows the erotic picture to Dr. Wick Sachs, holding the evidence with his fingers positioned much differently in the reverse shot. The plastic evidence bag is also folded while it was straight in the first view. (01:23:10)
Continuity mistake: The Gentleman Caller interrupts Naomi's execution (of the musical kind) saying that Bach should be "crisp." Naomi seen from behind puts the violin down, but she's still holding it in the close-up. (01:28:30)
Continuity mistake: During the press conference, when Kate is giving her speech the scene is lit very differently depending on the camera angle (the shadow cast by the microphones is a good indication of that). (00:54:30)
Continuity mistake: Cross is at the police station, enraged by the premature arrest. Kyle says "Alex, not all", and hands him a folder. The folder is turned in opposite directions between shots. (01:20:45)
Answer: I think you're talking about 'Silence of the Lambs,' not Kiss the Girls. The song is 'Goodbye Horses' by Psyche.
