I was wondering what is the best way to obtain authentic (but clear) audio clips for the voices of the characters in the films (as in creating units for them in the game). Now I could of course capture the actual film dialogues from a secondary recording device but that might not be the best quality audio and music and sound effects will be hard to minimize. How have people done this previously? Is there an online source that has clips of film dialogue?

Thanks
