Continuity mistake: 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. (00:38:10)
Hamster

Continuity mistake: When Trevor is fighting off the carnivorous plants that are attacking him and holding Hannah hostage, in one shot we see him punch into the mouth of one plant, causing his hand to become entirely covered in a sticky goo. In the following shots however, the same hand is now clean. (01:01:55)

Continuity mistake: 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. (00:03:50)

Continuity mistake: As Trevor and Hannah and the boy are traveling up the volcano on the cushion of steam, Trevor's arm constantly changes position instantly with different shots. Sometimes his arm is across Hannah's chest, then it's under her head, and back across her chest.

Continuity mistake: 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. (00:42:45 - 00:45:00)
Hamster

Hamster
Continuity mistake: 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. (00:15:20)
Hamster
Continuity mistake: When Sean is jumping across the floating magnetic rocks, as he jumps on the one that begins to flip him around twice, as he is flipped round the first time, it causes his small black utility belt (with the pocketknife and phone pouch) to fall off his waist, down into the abyss. In the following scenes moments later though, the same pouch/belt can be seen on his waist. (01:05:15)
Hamster
Continuity mistake: After Trevor and the others are submerged in the water they have soaked everything, but the book is intact and dry moments after that.

Chosen answer: Yep. The DVD comes in 3-D and 2-D versions. The 3-D versions come with (if I remember correctly) four pairs of 3-D glasses.
