Random movie textures

I have 5 movie files and want to have them randomly play on a tv screen. How would I go about setting up the random assignment.

Not looking for code, just a steer in the right direction.

I think the easy way to do it, is to set public vars to hold all of your movies.
After that just use the random function to determine a random number between 1-5.
Then us ‘if’ to decide which movie you want to play.
And finally, use gameobject.rendere.material to change the objects display.
