Visible crew/equipment: At the end, when Tom Cruise throws the knife at Dougray Scott's feet, there is a quick succession of shots consisting of the two in a fistfight. In one of the quick shots, as Tom Cruise is debating throwing the knife, then charges instead, there is a distinct black shape at the bottom right side of the screen that belongs to neither Cruise or Scott. The shoulder of a crewman who got a little too close, perhaps?
Plot hole: The virus ravaged Nyah is making her way to a cliff to kill herself when Ethan sends his buddies to save her. There is no way that the flight to her location would have taken that long unless John Polson decided to take Ving Rhames for a guided tour of the Sydney skyline first just in case he missed any of it. It's just a couple of minutes flight time for a helicopter at full throttle.
Plot hole: In the first night that Nyah is in Ambrose's house she meets with Ethan outside the house and they talk for about 1 1/2 min. Then we find out "Ethan" was really Ambrose with one of those "high-tech" masks. My question...After being in bed with both, how come Nyah didn't recognise Ambrose is about 5 inches taller than Ethan?
Continuity mistake: The 747 that crashes in the beginning of the movie has a fictitious airline name painted on the fuselage; but the dialogue uses a different name.
Factual error: The portrait of Semana Santa (Eastern) celebrations in Sevilla are absurd. Weird wooden constructions on fire (I guess it refers to Fallas, a celebration from Valencia and Alicante, around 400 miles away, in a tradition in which people burn cheap satirical and arty polystyrene sculptures with the arrival of Spring). Repetitive satanic hymns, fantasy castles, ritual drums, fireplaces and candles everywhere, effigies on sticks on flames, traditional clothes from somewhere in Central America mixed with San Fermín outfits and flutes (from Pamplona, over 600 miles away), frantic dances and women throwing flower petals over the crowd. I only miss some bulls dancing around in flamenco clothes while drinking sangría. The equivalent would be to portray a US festival in which Mickey Mouse rides a horse wearing a scary pumpkin mask while being carried by a leprechaun watching fireworks.
Factual error: The car chase between Ethan and Nyah is supposed to take place in Spain involving Spanish cars (plate's colour and the way numbers and letters are represented follows the Spanish code), but a real Spanish plate should have numbers and letters displayed as follows '1234 ABC' or 'AB- 1234-AB'.Sacha
Continuity mistake: When Ethan makes the spectacular leap during the rock climbing scene, you see him land vertically, as in he landed in a standing position, clinging to a rock safely, yet when it immediately cuts to another angle, he is already sliding down to the edge.
Continuity mistake: When Nyah and Ethan are in the tub at the mansion, one shot shows Nyah with the heels of her feet up, then it switches to where they're facing the bottom of the tub.
Visible crew/equipment: At one point in the scene where Tom Cruise is escaping with the antivirus, but before he gets on the motorcycle, he jumps and sort of flips and manages to shoot someone while upside down. When he lands, the ground ripples like a waterbed, revealing that it was some sort of pad to cushion his fall.
Visible crew/equipment: During the bike chase at the end of the film, a stunt man in full leathers and crash helmet can be seen on one of the bikes - none of the riders were wearing anything like that.
Continuity mistake: In the first scene Ethan is climbing - he makes a strange jump and he manages to move from one rock to another, but after that tremendous front-hit his t-shirt is perfectly clean...what soap does he use?
Continuity mistake: When Nyah is getting out of the "PALACIO DE JUSTICIA" building in Sevilla Spain, she is using a leather bag in her right arm, then we see a close up of Tom Cruise wearing sunglasses and watching her. The reflection of Nyah on the sunglasses is wrong, it should be backwards (the bag has to be in the left arm in the reflection).
