just a word of advice, if you're thinking of releasing the song with an intro like that to the public, it might be a breach of copyright. if you're going to license the use of a clip from a movie etc. it will be fine.
this is single-handedly the reason royalty-free voice sample packs are so popular among electronic musicians, because sampling is/used to be a large part of that scene and nowadays you need to be really careful about what you sample.
