Where to find stock footage

For massive destructions and flames coming out of pistols go to "Detonation Films.com". They are a company that provides stock footage, some for free and some not, so they can pay their bills. They have explosions, muzzle flashes, blood and more.

Where to find sound effects

Guns make sounds, cars make sound, crowds make sounds, everything makes a sound. You will need sound effects in order to make a nice movie. I personally use a site called "FlashKit.com". It has a large variety for movies and flash animations. You can preview the clips and then download them to your computer. Don't forget that there are also ambient sounds like birds singing and footsteps, not just guns sounds.

No movie is fun without music so go to "FreePlayMusic.com". They have a wide selection of non-copyrighted music that you can choose from and download. It is also categorized by Genre or Style.
