Find a project on github that is related to your interests and written in a language you're at least moderately good... or create something from the scratch. Find a problem and try to fix it. Even if someone already did that, doesn't mean you can't make it better. Don't pick large projects for contributions - you'll spend too much time just making sure that your contribution at least will be reviewed. You say you like movies, I'm sure there must be something related to that entertainment medium that you can contribute to.
