Goofs

The scar on Rita's forehead is virtually skin-tone is some shots (as if old and faded), and bright red (as if new) in others, although all of the action takes place within 24 hours.

When Cage wakes up after seeing where the Omega is, he realizes that he is hooked up to blood, and the blood bags are nearly full. After having a short interchange with the nurse, the bags are suddenly empty.

While Cage is waiting for Sergeant Farrell to tell him the number of push-ups he looks back, we see the two APCs coming straight towards him. After he starts doing the push-ups they show us the two APCs again, but now the second looks as if it just turned in from the corner.

In the first conversation with General Brigham, one of Cage's jacket buttons is undone. In the next shot, his jacket is neatly buttoned up.

The minivan that Rita and Cage drive in Europe is a Renault Espace Mk IV. However, the radio shown is from a Toyota Prius and bears no resemblance to the dashboard of the Espace.

When the drop ship hits a pile of cars, its front rises and its speed decreases; Rita's inertia should either make her hit the front console, or throw her out through the windshield. However we see her being thrown to the back of the cabin.

When Cage and Rita are training in the firing range, Cage is shooting in a 360 degree dynamic configuration (e.g. at opponents on all sides). Earlier we saw that the range is open at one end and clearly designed for a traditional static firing line. We are shown at one point that a bullet from Cage's weapon barely misses Rita. Shooting a fully automatic weapon in 360 degrees in such an unsafe fashion would not be permitted on a military base, as it would likely result in the death of Rita as well as the bystanders seen nearby.

As Rita and Cage are exiting the underground car park at speed, a barrier starts to raise at the top of the ramp. The side of these ramps facing oncoming traffic is essentially a 2-foot wall, there's no way a car could use it as a ramp, it would just plough onto it. Even if the car was coming from the other direction, the (actual) ramps used aren't wide enough to have both wheels hit it at the same time, especially a larger car like a jaguar.

At the end of the movie when Cage is looking for Rita for the last time, the other soldiers stand at attention and salute Cage. When Rita is found, she approaches Cage aggressively and demands to know "what do you want?" A Sergeant would never address a Major this way.

The farm's barn door displays a sign with a phone number starting with a 2. French nine-digit phone numbers are always prefixed either by a 0 or by +33.

Vrataski explains that she lost the power to reset time after she was given a blood transfusion. However, it is impossible for her to know this for certain as the only way to have proved it would be for her to die without time subsequently being reset, which would have resulted in her being permanently dead. It is established in the movie that Cage "feels" he lost his power. The same would be true for Vrataski.

Cage is identified as a major in the US Army, but is wearing the uniform of a US Marine Corps officer. The United Defense Force is made up of multiple military forces from various countries. While Cage wears a a US Marine uniform, his insignia are UDF. It is possible that a Marine uniform was adopted for American UDF officers.

In the reset where Cage decides to not approach Rita and undertake the mission on his own, Rita would ostensibly die on the beach in the manner portrayed in their first encounter. Thus Cage can't avoid involving Rita in defeating the Omega. However, he was most likely trying to figure out how to continue, before taking Rita with him.

In the first timeline iteration, when J Squad is first introduced and Farell finds the playing cards, Nance eats three halves of a card instead of two. Nance had actually torn the cards into three pieces.

As Cage wakes up, the first voice heard in the background is that of a native Spaniard announcer, saying "the supplies close in 10 minutes": Los suministros cierran en 10 minutos. This is gramatically incorrect; the announcement should be: La entrega de suministros termina en 10 minutos.

The armor worn by the military members is nearly useless. While it enhances their strength and it allows for rapid fire weapons to be used with no recoil, it provides the wearer with almost no protection from kinetic impact, bullets or flames.

When Cage first meets the General in his office the code-name for the following days action is stated as "Operation Downfall" - when you see the map that the general is using to illustrate this the top left corner shows "Operation Ruby Tuesday"

When Cage and Rita are talking in the car, both have hydration pack tubing coming down their shoulders. No mouthpiece is connected to the tubing.

The General's secretary is named Iris but the closing credits list her name as Julia.

The hat that Master Sergeant Farell wears in the beginning of the film was discontinued by the U.S. military back in the early 1980s.

"Big Ben" clock chimes 12:00 despite showing 12:35pm as Major Cage (Tom Cruise) wakes up in the helicopter en route to London to his initial meeting with Brigham the time-reset day before.

Incorrectly regarded as "Crew/Equipment Visible': At the Bavarian Alps dam, when 'Cage' (Tom Cruise) enters the building and rapidly turns to his left (where there is a large potted plant by the door) and aims his weapon, there is a sudden motion in the left background. This motion has been cited as a crew member ducking back out of site as Cruise turns toward them. In fact, upon close study, it is a branch of the potted plant.

Note that the reputed crew member appears as if they are carrying a mop or wearing a mop-like accoutrement. Note also that as Cruise turns suddenly left, the plant quivers slightly as if his weapon has brushed up against it. The motion by the plant perfectly coincides with the 'crew member' appearing to suddenly duck back out of sight of the camera when, in fact, it is a branch of the potted plant responding to Cruise's weapon brushing up against it.

This same branch/'Crew Member' can be seen for a fraction of a second behind Tom Cruise as the edit cuts to Cruise having turned back to his right.

At the Bavarian Alps dam, when Cage enters the building aiming his gun, in the left background close to a window, a crew member can be seen standing and then hiding from the camera.

On the map seen at the start of the movie, the capital of Slovenia, Ljubljana, was misplaced in Croatia.

The opening voiceover says, "They spread out from Hamburg across Europe." Hamburg is near Germany's north coast but the map shows the spread starting from somewhere in central Europe near Munich.

On the map seen at the start of the movie, the capital of Hungary, Budapest, was misplaced.

Lyon is not on the way to Germany.

The dam is identified by Dr Carter as "Curnera dam, in Germany". The "Lai da Curnera" lake indeed has a dam but it is not in Germany, it's in Switzerland.

When Cage and Rita have retrieved the transponder they should have used it immediately in General Brigham's office. Then Rita should have immediately killed Cage. That would have been the easiest and safest escape.

After Cage uses the transponder and finds out the location of the Omega, here is no reason for the ensuing car chase which results in him losing the ability. In fact, it would make more sense to get intentionally shot so that they have more time to find a way to reach the Omega's location.

Cage states that he has "inspired millions" to join the armed forces, through his televised campaigns, yet, despite being, presumably, a high profile character not one recruit or member of the forces recognize him.

The Mimics trap Cage to a German dam ostensibly to get their time-control power back by bleeding Cage to death. However, death by blood loss would be no different than any other violent ways that Cage died before (explosion, cut into pieces, etc.) since one dies after losing about half of one's blood, which means that Cage would still have the power after death by blood loss. The Mimics would have had to give Cage a blood transfusion instead.

Though initially it seems that it is Cage and Vrataski's first visit to the farm house, Cage later reveals that the two have been there many times. If so, they could have taken steps not to run out of gas, for instance by searching out abandoned vehicles from which to siphon gas long before the minivan runs out. Indeed, they would have had no reason to return to this particular farm house.

Towards the end of the movie Skinner, a British member of J Squad, says his "second grade teacher" was named Polly. The US grade levels are not used in UK schools.
