After EarthGoofs

After Kitai climbs/digs out of the pig hole,he finds he is being followed by the mother bird and is often seen holding his cutlass protectively and yelling at her to "Leave me alone!" In the following scene he takes his final breathing fluid, but there is also no sign of his cutlass. He builds a raft,floats down stream but his cutlass is forever lost after that & we never learn how he lost it.

Right before Kitai reaches the river, his father's cutlass is on his backpack. The cutlass disappears in the next shot, right before he starts building his raft, until Kitai picks up a new one at the crash site.

Before the crash, Cypher Raige straps himself into the chair with the X harness. In the next shot, he's in the background with no straps on. In the next shot after that, you can see he's strapped in again.

An arterial shunt is applied on the inner thigh, far from any arteries.

The ECG's run backwards.

When the asteroids get ejected from the wormhole along with the ship, they immediately begin to slow down. In space, however, they would continue in their speed until e.g. hitting an obstacle or entering the gravitational pull of a planet.

Cipher connects the stint to both ends, with the stint full of air. This is a fatal error. He should have let the blood flow through it and then connect it to the blood vessel in order to eliminate the air.

When Cypher tells Kitai to take the anti-toxin in sequence, he tells him to take the clear fluid first. Kitai grabs the opaque vial and administers it, then the second, clear vial. This does not appear to have any untoward effect.

When Kitai starts running up the volcano through the bushes to set off the beacon, the shadow of a moving camera crane appears in the lower screen.

The first night on Earth where Kitai is hiding under a log over a thermal hot spot, it is raining heavily. However, if the temperatures plummet so that the entire planet is frozen over every night, it should have been a heavy snowfall as opposed to a heavy rainfall.

While transporting the Ursa all passengers on the ship are required to wear life suits in case of an emergency but Cypher doesn't take one for himself. While it is established that the character is fearless, just because you are fearless doesn't mean you can't be prepared for emergencies.

When Kitai is followed by the baboon, his dad warns him about a creature approaching him. With his advanced technology he should have been able to see the whole group and warn his son about the even greater danger.
