Not really larp, but while surfing the net I found the following clip:
It's a fan film about the father of Aragorn, Arathorn.
The trailer was filmed in 2006 and was just a test. For a test the result looks awesome.
I'm also curious about the costumes, I might be able to 'steal' some ideas for larp costumes :-).
