You know, Casper van Diem was a perfect casting for Starship Troopers, that guy just straight up looked like an action figure. I don't mean a person they would model one after, an actual action figure.
He unironically looks like his teeth would twinkle when he smiles. But you want to talk about the real god tier casting decision in that movie? Jake Busey as Ace. Dude looks like he was grown in a petri dish for the sole purpose of playing the ultimate assclown.
