I'm a film director. A year ago I had this idea... I asked young parents on Facebook to record their kids imitating various animal sounds. I've got 12 audio files of 2-5 year old kids barking, meowing and chirping.
After a year I showed this video to one of my clients. They liked it so much that they bought it from me. Yes, it's an advert now. But it's still cute.
