Anachronisms 

A blue sailing ship passes by the island while the three kids are playing in the mud. When the ship turns to leave you can clearly see modern radar equipment high up on the mast.

When Emmeline is teaching the baby how to swim, she calls Richard down to watch. When Em is holding the baby, you can hear a child laughing that doesn't match any of the actors. Later, you hear the toddler Paddy laugh and it sounds identical to the laugh heard before.

After Paddy dies, and the children pack up the dinghy, the handmade toy boat is prominently displayed on top of their belongings. Years later, when they return to the original hut, Richard is digging through the rubble and finds what is left of the toy boat that he clearly took with him.

The night Em has the baby, Richard hears the drums and it's daylight. He goes to the other side of the island, it's night time. Then Emmeline has the baby and it's daylight again as it turns to dusk.

The lifeboat Mr. Button and the children take is a simple dinghy when it's still on the ship, but the first morning they are lost at sea, it has somehow acquired a mast and sails.

After Emmeline teaches the baby to swim, they go swimming together. In the underwater shots they have no clothes on but in a close-up of Emmeline, a little piece of clothing is visible.

When Emaline is sitting in the hut breastfeeding the baby the shot carries through without an edit towards Richard. Just as the camera pans away from Emaline you can see the actress double sit up quickly to make room for Brooke Shields to take her place when the camera pans back.

Errors in geography 

There are both macaws and cockatoos on the island. Macaws are from South America and Cockatoos are from Australia.

Factual errors 

When Emmeline walks in the water she accidentally steps on a fish and gets sick. The fish that the movie shows is called Stone Fish and in fact if you step on one the venom will cause excruciating pain and also shock, paralysis, tissue death and if not treated within few hours also death. Emmeline doesn't seem to suffer from any of these symptoms and it seems it takes some time until Richard finds her.

Plot holes 

Being stranded on an island for years, neither Richard nor Emmeline show any signs of tanning or sunburning.

Revealing mistakes 

Richard and Emmeline have both come of age on an island away from civilization. Both are clean shaven, however. While a teenage boy may not sprout a full beard Richard should at least show growing sideburns and some peach-fuzz on the chin. He even references that he is growing "all these hairs" on his body. Likewise, Emmeline's armpits should be hirsute. How did they learn to shave and where did they get razors?

As Richard and Emmiline observe the crab coming out of the mouth of Paddy's "dead" body, you can see his nostrils flaring as he breathes.

When Paddy and the kids first sight land and begin to sail toward it, the mountainous coastline of a large land mass can faintly be seen behind them, indicating that the island is not as remote as we are led to believe.

When Richard and Emmeline have a fight she sleeps in her own shelter during a storm you can see a rope at the top of the shelter pulling it down.

When Richard goes fishing from the boat and his catch is attacked by sharks, tearing the line from his hands, a rope can clearly be seen dragging the first (presumably dead/fake) shark through the water
