Good fun doing stuff like that, but watch out for the ten minute limit on YouTube, I had to chop quite a lot of good footage and stuff out of my Battle of Briatain 'story of R6753' one I linked on here a while ago (this one:
).
You might find the Shockwave Wings of Power II B17G for FSX useful in making close-up shots, as it is an amazing model. Their bf109E might also prove useful, although the Shockwave bf109 exterior model has got a slight error on it (I know this because I just reviewed it for AVSIM and marked it down because of that), so the 109 in BoB2 might also suffice. If you are doing a late war movie, you might find the Flight Replicas Me262 useful (just reviewed that for I've AVSIM too, been busy LOL)
As with my Spitfire one, using 'The Movies' game for close ups of crews is handy and well worth trying, as the personal touch it lends to this kind of movie makes it stand out from all the shots of planes flying around.
