I'm thinking to build an android and iPhone app, with short jokes, phrases from movies. The length of the jokes is 2-3 seconds maximum.
I don't plan to make any money from this app(by advertising or any other method), but i think I'm not allowed to use parts of movies.
Is there any way of using parts(sounds/voices) from movies but to not have troubles. The thing is that are some movies(friends, big bang theory, seinfeld, 2.5 men), which i like to listen their jokes when i'm in subway or something. I'm software engineer an I'm capable to build such an app.
