Movie and audio timed together with fireworks.

Hi I'm new to arduino and i was looking for some helpful tips on my project. I want to shoot timed fireworks with a movie and the audio from that movie. I will be using a arduino mega and I can also use my laptop because i know the arduino can't do movies by itself. The firework is an easy ignition and only needs a small amount of power for the ignitors. Please let me know what you recommend for this project. Thanks
