No problem, always happy to talk about the Teutonic Order!
Also, yes, that scene in Kingdom of Heaven was a mistake, and they were meant to be Templars, who apparently got some future surcotes and helmets. Must have been an executive decision on Ridley's part...
Costume Guy: Hey, director dude, GDFB says they only have 80 of the "Templar" surcoats in stock. But they have 20 "Two-tonics" that we could buy too.
Director Dude: Okay so what's the difference?
Costume Guy: They said it's almost all the same and just a black cross instead of a red one.
Director Dude: What are our other options?
Costume Guy: Ask your mom to sew us the other 20 we need.
Director Dude: It's a short scene, get the two-ton-whatever, it's close enough.
