The Great Gatsby

When Gatsby meets Daisy at Nick's cottage, it is 4 pm.

Later, they look across the water at Daisy's house in East Egg, with the sun just over it - which would only happen in the morning.

The "French" phone shown as they talk about the intrusive unwanted guest calling Tom wasn't invented until about the mid-30's.

In 1922, you still had to hold the candlestick phone in one hand and talk into the mouthpiece while holding and the earpiece up to your ear.

The story is set in 1922, but Gatsby's yellow car is a 1929 Duesenberg Model J.

The tenor saxophonist at the Gatsby's mansion party is holding the saxophone incorrectly.

The proper way to hold a saxophone is with the left hand on top and the right hand on the bottom.

The player in the film is holding the saxophone with the right hand on top and the left hand on the bottom.

When Daisy is introduced to Gatsby in Nick's cottage, Gatsby sneaks out the back door and emerges through the front completely soaked due to the rain.

However, in the next shot, which dialogue indicates takes place with little to no time passing, Gatsby is completely dry.

When Gatsby was at Daisy's Louisville home, the opening shot showed him with two ribbons on his chest but in subsequent shots the ribbons were missing.

Beyond that, one of the ribbons was the World War I Victory Medal that was awarded to soldiers after the war and clearly this scene was before Gatsby shipped out to France, so there is no way he would be wearing it at this time.

Some establishing shots of Manhattan show the Chrysler Building and the Empire State Building under construction.

The film takes place in 1922.

Construction on the Chrysler Building began in 1928 and on the Empire State Building in 1930.

When Nick rides with Gatsby in his car, Gatsby passes a truck and waves his hat to him.

In the next shot as they make a turn, his hat is on his head.

In the next shot, it's in his hand waving to the truck again.

While Gatsby and Nick drive to lunch, Gatsby's is telling a story.

In further shots, however, his mouth is not moving.

When Nick discusses the tea invitation with Gatsby in the garden, there is a spot on Nick's left lapel.

It disappears in the very last shot.
