When Frank is explaining to the limo driver his new role as his assistant, Frank points one of his handguns directly at the driver. A former Secret Service agent would always be aware of the direction of his muzzle, and would never under any circumstances point it at someone absentmindedly.
As mentioned above, for a supposedly trained professional, Frank Farmer commits at least two violations of basic weapons safety rules by pointing a loaded weapon at people he doesn't intend to shoot. First when he is discussing security with Henry, Frank points his .45 directly at Henry. Then, during the incident at the cabin, as soon as he chambers a round in his .45, he points it directly in Nicki's face as he tells her to stay still.
When Frank discovers that Portman is not the Oscar host's bodyguard, and in fact the person who has been trying to kill Rachel, he does not make any attempt to alert the Oscar's security or the police stationed there about Portman, something a trained Secret Service agent like Frank would have done.
There seems to be some confusion over the lead character's name throughout the film. She is listed as "Rachel Marron" in the credits, but her last name is spelled differently in some of the death threat notes. Also, a fan holds up a brightly-colored sign when the limo pulls up to the club halfway through the film and it says, "We Love Rachael" with an additional "a".
In the final scene depicting Frank serving as security at the political function, the clergy is asked to offer the "benediction" at the start of the meeting. The benediction is offered at the end of a service, not the beginning. The prayer offered at the beginning of any type of service or meeting such as this, is the "invocation."
After Frank's fight in the kitchen in the hotel in Miami, he goes straight on to the terrace of their room where he suddenly remarks that Rachel is sitting behind him. After begging Frank to stay by her side, Frank accepts under a few conditions: One of them is that Sy Spector must be fired. Rachel agrees but when they're back for the Oscar's ceremony, he is still her manager.
Frank Farmer speaks to Ray to ask for help at the Secret Service. As Frank adjusts Ray's collar, he has a lit cigarette in his mouth. But as the camera cuts to a side view of Ray smiling, and he has no cigarette in his mouth.
Tony, Rachel original bodyguard gets hit by Portman at the Oscars scene with a left hook and a special nail type ring on his right eye . Tony brings up his right arm to cover his right eye. Then he comes out later holding his left arm to his bleeding left eye. In the final scene at the airport strip, again he is wearing a patch on the left eye that he "lost".
Frank arrives at the mansion for the first time and is talking to Henry. The camera angle shows Frank from the front, starting to button his suit coat. A close-up then shows Frank, looking down as if he's finishing up with that buttoning business. The next shot is of Frank from the rear, hands in pants pockets--coat obviously unbuttoned. He takes his hands out of his pockets, starts to button the coat--and while still doing it, the camera shifts back to the front view--the coat is already buttoned, and Frank's hands are already down at his sides.
When Rachel is watching Frank watch her film clip, Frank is leaning forward from Rachel's view, but when it cuts to a close shot of Frank he is leaning back in the chair and then begins to lean forward.
When Frank is being wheeled out after he is shot, he has no oxygen on. This is a huge mistake and even the lowest trained technician would have done this. The fact he has I.V. fluids running show they are higher trained. Even if done to allow the viewers to see his face, many movies have them removed by someone to allow a short conversation. Since blood loss is obvious, not having oxygen is something that would certainly bring the credibility of the movie down drastically. It is unlikely that even the newest practitioner would neglect or forget to put high flow oxygen on a gunshot wound victim.
A mock copy of the Hollywood Reporter newspaper announces the Oscar nomination for Whitney Houston's character on the same pages as the ratings for Game One of the World Series. But the Academy Award nominations are announced in February, months before the World Series in the Fall.
When Rachel is handling the katana at Frank's place, it is clear from the regular scalloped pattern ("hamon") on the blade that it is not a real katana, but a cheap ornamental replica. Real katanas have an irregular hamon. But that doesn't mean it couldn't be sharp.
In the dive bar scene where Frank takes Rachel on the date, an extra seems to look straight into the camera and raises his beer towards it as Frank and Rachel walk to the dance floor. On a closer look he is cheering to the blond woman in the front.
If you look closely as Rachel, Fletcher, Sy, Devaney, and Tony are walking out of the mansion on their way to The Mayan nightclub, you can see that this is not DeVaughn Nixon playing Fletcher, but another actor.
When Frank takes Rachel's scarf and throws it in the air to be cut in half as it falls over the sword edge, the scarf is clearly prepared for the shot.
If it hadn't been, the weight of the scarf wouldn't be sufficient for it to be cut on a horizontally held edge. It would either have to weigh more, it would need additional force pulling it downward, or the blade would have to be angled so that the scarf slide along the edge.
