Absolute Anime

Berserk
Last Exile
Trigun

but mainly Last Exile

Umm... I'd say a good couple animes that would be preety cool are the following.

1. Area 88
2. Rurouni Kenshin
3. Azumanga Daioh (not really an action)
4. Wolfs rain, but thats only probable.

i'd love to see Elfen Lied in Live action. god, the violence would be so awesome i reckon FMA would work on a lesser degree

but, my overall decision for live action...

Orguss 2 no argument, violence, action, great plot, awesome characters, it would so rock

Naruto could work
