When parking because of traffic, the car carrying Caldwell and Kitty bumps into another parked car. When Caldwell gets out of the car, the car is seen parked with some space in between.
About 1:15 into the movie Ari asks Kitty how many Minutemen were at Concord. When she doesn't know he answers 77. But he was mistaking Concord for Lexington Green, the first of British encounters, where there were only 77. By the time they reached the Old North Bridge in Concord, there were over 400 minutemen.
The film repeats a historical error contained in the original novel, when Karen tells Dov about how King Christian X of Denmark publicly wore a yellow Star of David in defiance of a Nazi order that all Danish Jews do so. In fact this incident never occurred - Danish Jews were never ordered to wear the yellow star.
Kitty's late husband Tom was killed in a minor border incident where Jews blew up some bridges. The last photo taken by Tom was a fighter strafing the truck. The Jews had no fighter aircraft.
The German SS at Auschwitz executed all the Sonderkommandos and selected a new crew 13 times, hence only the last 14th survived. No Jew, therefore, could have had the experience of exploding dynamite to create mass graves. As this process well predated the installation of the crematorium, his Sonderkommando unit would have been liquidated long before liberation.
During the prison break when the truck is blown up at 2:37.06 the bomb explodes a split second before the man turns the crank on the detonator.
At the beginning of the prison escape, one prisoner runs to the locked door to light a 4-6 inch long fuse on the device mounted to the door. The fuse burns for a few seconds, the bomb then explodes with at least 2 inches of fuse remaining.
When Karen arrives in Gan Dafna, one of the girls on the steps (about center frame) looks at the camera just before the cut.
Early in EXODUS, Kitty appears wearing a square dress outfit with no sleeves and bare underarms, a fashion totally out of place in 1947.
(Around 1:22) The whole dialog during the "Joa, take the dog out' scene is dubbed over, as is very obvious from the reverb that stems from the studio the recording took place in.
There are many moments throughout the film where the shadows of the camera equipment can be seen.
Karen tells Kitty that "when you're 16, you join the Palmach. Everybody joins." In fact, the Palmach was an elite force of specially selected fighters within the Haganah. It was not open to general membership.
When Ari gets out of the car, his head hits the corner of the door and he touches his forehead. Eva Marie Saint barely restrains genuine laughter.
