Well it will be if I ever get a budget. But P-51 and pilots are cheaper to do than VIICs.
I'd have to build a VII interior. But in Foo Fighters all I had to do was put the actors in a CGI cockpit. And the only reason I could even afford that is I do CGI for a living and have all the goodies to do it. But yes I WW2 submarine movie would be a desired next project if I can.
Thanks!
