Pifias

When Indiana is fighting a pirate during the attack on the ship, he performs a somersault over a set of stairs in which his fedora clearly falls onto the top stair. Upon landing at the bottom of the staircase, Indiana readjusts the hat on his head.

Many of the pirates are armed with M-1 Garand rifles, a weapon that would not be invented until the 1930s.

The singer/pirate captain is obviously dubbed also her lips don't match the words.

When Indy and Remy chase the steamer out of Alexandria, the ticket seller informs them that it will stop in Bombay. However, when the red line is shown on the map, it goes straight from Port Said to Java.
