Ice Age

When Soto describes his plan for bringing down the mammoth, Zeke and Oscar swap positions between shots.

At the end of the movie, Runar places the necklace that was around the baby's swaddle on Manfred's trunk.

A few moments later, the necklace has disappeared.

During the fight with the dodos, Diego disappears when Manfred is keeping the melon away from the dodos.

When the melon goes flying, Diego is back beside Manfred.

In the first shot of the human camp, the camp is on the left side of the river that leads to the waterfall.

During the tiger attack, the camp switches places to the right (note where the baby's mom jumps).

Sid's position beside the fire changes when his tail catches fire.

Sid steps in poop with the first step he takes, but in the previous shot, there is nothing within two steps of him.

At the end of the movie, Scrat is seen frozen in ice.

The ice is floating on the ocean with 90% above the water.

The ice should be lower in the water with only a small fraction above the water line.

Only a huge wave would then be able to wash Scrat onto the beach.

In the first camp-out scene with Diego, Diego is sleeping close to the rock wall when Sid returns.

There is an overhead shot, and he is only a few feet away from Manny and Sid.

Later, in another shot, just before he gets up, he is back by the wall.

When Roshan is crying and they're trying to figure out why before the melon scene, Sid picks him up after the notion of BM is mentioned.

When he says 'Why am I the poop checker?' he spreads his arms, and is no longer holding the baby.

The camera wasn't on Manny long enough for Sid to put Roshan down.

Animals, from many different epochs and continents, mingle in 10,000 B.

North America.

During the sliding scene, Manny slides through some spikes on a slab of ice right after Roshan, who, weirdly enough, got through it unharmed.

When the sabertooth pack is chasing Sid and he "skis" away, Sid is kicking up powder and leaving tracks in the snow, but during the early stages of the chase, his pursuers are running across the top of the snow leaving no tracks.

Just before Sid comments that his "feet are sweating" there is an overhead shot of all three main characters walking along the snow.

Their feet are moving but their bodies are moving forward far faster than their steps would take them and they appear to be sliding forward on the snow.

The first animal to step on Scrat in the opening is a mammoth, yet no mammoth is visible in the long shot of the crowds of animals.

In fact, no mammoth other than Manfred is seen throughout the sequence.

With this, a large bird also steps on Scrat, but no birds are seen in the crowds.

We also only see two legs of each animal stepping on Scrat even though three of them are quadrupeds.

When Scrat's coconut falls from the tree, it has already had its husk removed.

(The directors confirm this on the DVD commentary.

They may have been worried that a lot of their audience would not recognize a coconut with its husk on.

) In the opening sequence Scrat is running along a valley floor when he is squashed between two colliding mountains of ice.

When he is ejected from the crevasse, he is suddenly thousands of feet above the valley floor.

The mother lifts the bundled baby from the rushing river to lay him on the bank.

The bundle changes from glistening wet to bone dry in one cut.

The ice cornice that forms the avalanche breaks loose in sharp chunks with very square edges, but when they hit the ground they are all completely rounded, not an edge on any of them.

The baby accidentally slides down an ice tunnel, which appears to be roughly twice the size of the baby in diameter.

The animals pursue by sliding down the same tunnel, which has somehow expanded to twice the size of the mammoth.

In the mountain pass scene, the lighting on the clouds shows that the sun has set both in front of the animals and behind them at the same time.

At the start of the cave drawings scene, the baby babbles, but his mouth doesn't move.

After Sid, Manny, Diego and Roshan are trapped inside Diego's "shortcut" by the avalanche, Sid walks straight into a slab of ice at face height before falling down and getting his tongue stuck.

When he gets up again a few seconds later, the slab of ice has disappeared.

When the mother pushes the baby towards Manny, the baby is on a sloping rock and Manny pulls it towards him with his trunk.

The next moment the baby is on the flat ground beyond the sloping rock.

For that to happen, Manny should have either pulled the baby right off the edge of the slope to the ground with a thud or lifted and gently lowered it.

In the ice cave, Sid turns around a bend, looks right (heaves a sigh of relief), and then looks left to find the scary fish fossil.

Then he turns right and immediately sees the dinosaur fossil.

There was no dividing wall or corner between the 2 fossils, so the dinosaur should have been visible to Sid even before he saw the fish.

In the rain scene, when Sid asks Manny "So what about you? You have family?", Manny turns away from Sid.

The camera is on Sid in this duration, so we don't get to see Manny turning.

The shelter is so small and snug, it should be impossible for a mammoth to turn around without first coming out.

When the baby falls out of the swaddle while Sid is climbing up the cliff, the swaddle disappears only to reappear much later in the movie.
