Strangely enough, if I were going to do a Wing Commander movie, I wouldn't focus on Blair or the Tiger's Claw or anything. I'd do something separate and stand-alone that would be able to stick viewers into the WC world without trampling on previously established characters. Perhaps a depiction of an earlier conflict in the Kilrathi war, with a running parallel to Wing Commander 3 with the Rapier replacing the Excalibur (and obviously no Kilrah run
For the actors, I really couldn't say. I think I would have to follow in Lucas' footsteps, and pick out some little known actors who have good chemistry together, and a few big names (preferrably with stage experience) to round out the cast. I think Roy Scheider would be fun in a command role, he would just have to cut the patches off his SeaQuest uniform and be ready
. I of course would love to have Ian McKellan in some role, but I'm not sure if he'd be good as a Terran. As a Kilrathi noble I could see it, but it would mean that he'd be limited in many of his emotive responses, what with a big mechanical mask on his head.
I think a good addition would be Levar Burton in his Roots years. They guy's got really expressive eyes, and that would be a big necessity what with the flight helmets.
I will admit that when it comes to the Wing Commander universe, I see WCIII as the pinnacle for set design. It's functional and sparse, yet still has a mild romanticism about it (and it had the best cats). So very much a WCIII style for set design and costuming.
Now for the music. I hate to be cruel and a pompous ass, but the Wing Commander theme stank. With little to no running chorus or established movement, I always found myself blinking, trying to grasp onto something to hum along to, and never found myself able to. I'm not saying that it had to be John Williams (who I think is overrated), but something like, oh, I don't know, Alan Silvestri would be good to capture the Space Opera style.
Now for the space battles, which is honestly what it's all about.
Obviously, CG is what one has to do for the battles, but an up close look will be required. Instead of modifying modern or older planes, I'd pull a Star Wars: Plexiglass and the Hitchcock method, with the only establishing shots being CGed. So some people might think the ships look fake, they'll still gasp when a Scimitar flies through a Fralthi launch bay and blows a bunch of stuff up.
Anyways, that's what I'd try.
