Every good geek knows that Star Trek is loaded with Shakespeare references. Mostly in Next Generation, where Captain Picard just quoted it all the time, and Data kept performing it on the Holodeck, but also in the original series and the movies as well.
I found a site that tries to track as much as it can. It’s pretty impossible to get them all, given how many episodes Star Trek ran through, but it’s a start.
One of my favorites has always been Star Trek VI, in particular during the final battle scene where Christopher Plummer (playing Klingon General Chang) cries, “Cry havoc! And let slip the dogs of war!” Gives me chills. Even better for a whole different reason is when the shot switches to the Enterprise, and they can hear Chang taunting them over the speaker:
Chang: “I am constant as the northern star…”
Dr. McCoy : “I wish he’d just shut up.”
