- Fridge Brilliance: The idea to mix sperm to get the perfect man is, of course, ridiculous. Of course, since one of their fathers looks a lot like Julius, you have to wonder if Traven didn't add a bit of his own "genetic material", resulting in Vince, making them, technically twin half-brothers, which is not unheard of.
- It was probably supposed to be an early genetic engineering experiment, attempting to blend the genetics of the various men into a single batch of sperm, rather than just dumping a bunch of sperm samples in one vat. This was before Genetic Engineering Is the New Nuke, however, and they simply didn't bother to explain it, either figuring the audience would get it anyway or wouldn't understand even if it was explained.
- Mixing sperm together doesn't somehow cause genes to get swapped, but the resulting chemical warfare among the sperm competing for fertilization does bias the child toward being more effective at reproducing.
- Hilarious in Hindsight: Julius and Vince's conversation while posing in their brand-new matching clothes. Guess which "icy" character Arnold ended up playing:Julius: Do I look cool now?Vince: Mr. Ice!
- The Penguin and Mr. Freeze find out they are long lost twin brothers.
- Ho Yay / Incest Subtext / Twincest: Believe it or not. Julius is a bit overly loving toward Vincent, Vincent doesn't mind after the first five minutes, the two get along almost perfectly, dance together with no though, hug constantly...
- True fact: Twins have a strong tendency to touch one another more than untwinned siblings, with no sexual connotation. Untwinned persons tend to see it as sexualized because they have no frame of reference.
- Narm Charm: The entire movie. Arnold Schwarzenegger and Danny DeVito as twin brothers? Laughably stupid, right? Despite this, the movie has a fair amount of touching familial moments between Julius and Vincent that make it far less silly than one might believe.
- Retroactive Recognition:
- Tear Jerker: The Twins are reunited with their mother. Being an upbeat case, it doubles as a Heartwarming Moment.
- The movie actually has a fair few of them, as much like Junior both Arnold Schwarzenegger and Danny DeVito apparently decided to act the ''shit'' out of the movie despite its silly premise.
YMMV / Twins
