Man!! That poster you made up is beautiful!8) Lovely stuff. As to a movie being made about 'Bubi' Hartmann.. If it happened it would, like you said be an amazing story ( if done correctly) but I don't see hollywood touching it. Perhaps funded by European money?
I've been told the unit will stick with 109's much like JG52 did, probably convert to later varients like the K4 towards end of comic series. But FW190's will make appearances in the comic as other fighter units fight alongside Kurt's pilots :)
