Well I mean one big action scene in space. There would a shit ton of establishing shots, but those won't eat up your budget as much as fast paced space action. I mean you could spread out the budget for a lot of shorter space sequences, but I think it would be better to have one large amazing scene that people would talk about then little ones that become common place. There would be lots of the Bebop taking off and landing and traveling through space gates, but there would be only one sequence with say the Swordfish and whatever Faye's ship is called dog fighting with bad guys. And besides once you do one time type of action you don't want to do it again in the same movie. The viewers will just see it as something they have already seen.
And by low budget I'm talking maybe 40-60 mill. That really isn't low budget, but for a movie like this it would be pretty low. I mean you can make a professional looking Hollywood movie for 5 Mil...but it's going to look like Clerks 2, and not Avengers.
If I was writing a CB movie the big last action scene would be a Spike vs. type scene. Much like we saw in say ""Pierrot le Fou" or the end of ""The Real Folk Blues". Jet, Faye, and Ed would have to find themselves someplace else tied up with maybe and underling or something. But all of these would be done in a more closed setting...I mean if anything the Jet/Faye/Ed stuff would be the more pretty to look out, because I wouldn't want to detract from the conflict of Spike.
I mean at the end of the day despite how pretty it is, BeBop is more Noir then it is Sci-Fi. It has more in common with say The Maltese Falcon then it does SW.
