No point to this tangent, it’s just running through my head.
People with two first names (last name is also a common first name) are confusing, and it’s extra annoying when they’re celebrities. I put this into Heroes are Easy, People are Hard with the doctor no one can remember the name of, Clark Evans or Evan Clark. That’s a nod to Chris Evans and Clark Greg (Phil Coulson actor--is it Gregg? That’s less bad), of course, because it’s a Marvel fic, but actually the worst offender in Marvel is probably Sebastian Stan.
If you’re going to have two first names, the more unusual and/or longer one should be the last name. It just doesn’t feel balanced otherwise.
Oscar Isaac is also trouble.
And then there’s fictional characters, because keeping real people straight isn’t difficult enough! In Stargate, look no further than the main characters: Daniel Jackson! Jack O’Neil! Sam Carter! (At least Sam is short for Samantha. If she were a dude, given how often they all call each other by last names, I would have taken several episodes to be sure if he were Sam Carter or Carter Samuel.) And then later--CAMERON MITCHELL. Were they doing this on purpose? “How few actual surnames can we use on this show?” “Hmm. Give the general one. And then we’ll have alien characters instead of actual last names.” “Sounds good!”
I have no point here. I’m sleep-deprived enough be the cognitive-impairment equivalent of slightly tipsy. But I have OPINIONS.
PS. Harrison Ford kinda has two last names.
PPS. I actually can’t quite place the general’s name from Stargate, and if it’s a first name too, like David or something, I actually suspect the writers had something against last names. Maybe they promised to name a character after too many of their friends, and were like “No, we have to get Mitchell in, I lost a bet, and I promised!” “Okay, fine, we’ll change this new Cam character’s last name. Smith is boring anyway.”
