Lloyd's Klingon delivery is so wooden and features so many unnecessary pauses between each word that I'm shocked the movie's big twist wasn't that Kruge and Kirk were long-lost twins. Does this make Christopher Lloyd a bad actor? Let me answer that with another question: How dare you? Christopher Lloyd is a goddamn treasure and a powerhouse performer. He just has trouble putting his heart into made-up lines that must sound to him like a jammed printer.
They don't prepare you for this kind of stuff in acting school. Just ask Dan Hildebrand whose Valyrian on Game Of Thrones sounds like, well, like a jammed printer: Clunky, forced, and it makes me want to hit him.
"Could you give me some pointers?"
You see the same problem with Neytiri's parents in Avatar or with pretty much every Martian in John Carter. All of them needlessly accentuate every word in their lines because to them it's just random noise that they had to memorize by ear.
But now check out Alycia Debnam-Carey speaking Trigedasleng, the fictional language from The 100.
She sounds pretty good, right? Maybe it's because she's young and therefore grew up in geekier times, so her brain doesn't subconsciously want to give itself a wedgie for trying to master a made-up language. This would certainly explain Emilia Clarke's excellent Valyrian or Zoe Saldana's fluent Na'vi.
Then there's Elyes Gabel, who played Rakharo on Game Of Thrones.
He was the one who died horribly and out of nowhere.
