For WWII war- bird geeks!!!!Please help!?

Hello!Can anyone tell me what P-51s they used in a) Saving Private Ryan, b) Band of brothers ( not sure if they were even real in that one....seemed a bit CGIed....but not sure). I kinda thought they used Ferocious Frankie (which would make sense since its based so close to their filming location) and one other in Private Ryan but not sure?Any help appreciated....cheerio!
