Star Trek: Deep Space Nine (1993)

Doctor Bashir, I Presume? - S5-E16

Character mistake: In the scene in Sisko's office where he has contacted Rear Admiral Bennett, Bennett says "Two hundred years ago, we tried to improve the species through DNA resequencing, and what did we get for our trouble? The Eugenics Wars." This puts the wars in the 22nd century, and differs from every other mention of them, where they occurred in the late 20th century, not the 22nd century as Bennett implies.

Doctor Bashir, I Presume? - S5-E16

Factual error: When Captain Sisko introduced the head of JAG to Bashir's parents, he pronounced "Rear Admiral Bennett" but Bennett was wearing the rank of Admiral (2 X 4 pips enclosed) instead of Rear Admiral (2 X 2 pips enclosed).
