Continuity: When Trevor, Hannah and Sean are being pushed up in the T-Rex skull by the geyser, they are laying in the skull and you can see that there is harness rope that comes out from behind Trevor and Hannah's back (that they are laying on). But in the shot when they are pushed out the mountain by the geyser and reach their highest point (before they start falling back down to the ground again) there is no rope visible behind them or in the skull at all. In the following shot as they fall back down to the ground, the rope has reappeared.

Revealing: After Trevor has been lowered above the pit of magma, in an attempt to light the magnesium walls with a flare, we see shots of Sean hanging over the edge of the inside of the T-Rex skull. Sean's hands are resting on a large tooth in the skull, which clearly shakes like a fake prop each time he touches it.

Continuity: After leaving the lagoon area and exploring the rest of the 'Center of the Earth', the size and appearance of the wet patches on everyone's clothes, especially on the front of Trevor's jumper, continue to change from smaller to larger to darker and lighter, etc.

Factual error: When Trevor, Sean and Hannah enter the cave full of emeralds, rubies and diamonds, you can clearly see that these precious stones are not in their rough, natural forms. Instead the diamonds are crystal clear and look shiny and polished. In reality they would be rough and have a murky yellow tint to them.

Continuity: When Trevor is sitting at the table flipping through the copy of the 'Journey to the Center of the Earth' book he found in Max's box, his location in the book keeps drastically changing from shot to shot, from almost at the start of the book, to the back and to the middle, and so on.

Continuity: After Trevor and Sean clamber out of the lagoon that they landed in, they begin to remove their jackets because they are soaking wet. However between sudden shots, the beanie hat and headlight that Sean was wearing on his head instantly vanishes, with no time for him to have removed it himself.

Continuity: Trevor falls a short distance to the floor after Hannah cuts his harness ropes with a knife. After he hits the floor and the ropes fall onto him, between shots the ropes laying all over his body and face keep moving, disappearing and appearing.

Visible crew/equipment: When Trevor is outside in the street greeting Sean as he sits in the car, Sean then gets out of the vehicle. As she gets out and stands by the car talking to Trevor, you can clearly see a large white reflecting board reflected in the backseat door, behind Sean.

Continuity: After the glowstick has been dropped down the chasm; and the shots goes back and forth from Trevor to Hannah as they talk, you can see from shot to shot that the torch in Sean's right hand keeps disappearing and reappearing.

Continuity: After Trevor saves Hannah from underwater and they are all laying on the rocks, Hannah's wet stringy hair keeps on changing position and the wet hair that is stuck to her right shoulder keeps disappearing then reappearing back on her shoulder during the scene.

Continuity: As Trevor frantically cleans up his lounge area, he starts picking up plates and foil takeaway dishes, collects them all and places them on a shelf. But in the next shot all the plates/tins have suddenly appeared on the central table in the lounge.

Continuity: As Trevor is telling Sean to check his watch in order to time how long it takes for the glowstick to reach the bottom of the chasm, Sean removes the torch from under his neck and points it onto his watch. Suddenly in the next shot the torch is back under his neck.

Continuity: When Hannah is tending to Trevor and Sean as guests in her house, she brings three mugs over and places them on the table. Between shots the three mugs swap their places; you can easily see this by comparing them in relation to the book sitting next to them.

Continuity: When Trevor gets home from work and sits down in his lounge, between shots the sheets hanging over the chair he is sitting on change and items (such as a stack of books, newspaper, etc) suddenly appear on the radiator behind him.

Continuity: When Trevor and Sean climb out of the lagoon, they realise Hannah is still underwater so Trevor dives back in to rescue her. When he retrieves her from the water and they all scramble back onto the rocks, Trevor leans his head back onto his backpack. In the next shot his head is now resting on the rocky shore below his backpack.

Continuity: After trying to tidy up the lounge area, Trevor gives up and resorts to throwing a large blanket over the central table, which he grabs from the sofa. After he picks up the blanket, between shots the position of the items on the sofa changes and also a cushion appears from nowhere.

Continuity: After Sean lands on the beach after being carried away on the kite, the position of the ropes that are attached to the sail, laying on the beach keep changing position. Also, Sean removes the ropes that are wrapped around his arms after he wakes up, but after he drinks some of the beach water, the ropes are wrapped back on his arms.

Continuity: Trevor is going over notes scribbled in Max's copy of the book on the airplane. As he talks to Sean about the notes and how he is trying to decipher the Sigurbjorn Asgeirsson notes, in the first few shots of these notes most of them are written in clear jet black ink, nice and new. But in the closeup as Sean runs his finger down the notes, the same writing is now differently written and the ink looks much more faded.

Continuity: When Trevor finds the copy of 'The Journey to the Center of the Earth' inside Max's box, although the title is spelt this way on the front cover of the book, as he looks through the pages, on the insides of the book you can clearly see the headers spelling the title as Centre instead of like Center on the front cover.

Continuity: As the T-Rex skull comes to a sliding stop at the bottom of the hill, Trevor, Sean and Hannah get splattered by berries. In the first shot there are a lot of berries on Trevor's shirt and face, then in the next shot there is hardly any and then there's a lot again in the third shot.
