Yep, listening one night at campfire is all you need to do to absorb a foreign language. 

I think you err in taking it so literally (assuming you’re being serious).  I took it as a time-compressed montage of a months-long process.  They had to film something, right?

13th Warrior? Love it. Definitely over a period of time considering where they were when it started and where they were when he finally started speaking.

It’s also very much a filmic trope of John McTiernan.  It’s just like that scene where the onscreen language for everyone changes to English in Hunt For Red October, even though you know they’re still speaking Russian.  It’s the narrative language that’s changing.

right, it’s a funny trope. The movie isn’t about him spending time learning this language and we won’t have him speaking through an interpreter the entire time. Still just looks like one campfire night and the words flow and what was that about my mother?!
