Nice! Depends what you want to see done with it and what ya got...
If you have a full length movie and would love to see it on the big screen some day, you'd have to get an agent (some are called literature agents) but don't worry they don't cost anything until you sell the script. They don't get paid unless you get paid. It's a touchy subject because I guess you could do it without an agent and get lucky. Some hire lawyers to make sure everything goes okay and such.
If it's full length but you don't feel the big screen is for this movie, you could look for producers or directors wanting a script... I have a lot of websites on this.
If it's a short film, it won't ever see big screen (unless you have a screening at a theater). You could do the same thing and sell it to small time people. Or make it yourself!!!
I've made a short film (for a contest) it was super fun and didn't cost that much, I had a partner and we probably spent $500 each. But you have to have a lot of friends willing to help and be able to edit the movie too!

My advice is to read up a lot on it! Read some books on "how to write a screenplay". There's tons if you need suggestions or help let me know.
Also I have a lot of websites book marked if you need anything!


This movie takes place in Pittsburgh!

Thanks for the reply! I'd very love the website thank you very much !

I say your movie should have a sad ending, just to go against the norms. If you want everything accurate, and it's about addiction, then it'd make sense that no positive resolve comes from the whole encounter. (Think like Italian neo-realism.) The detective ends up going to prison in the end, and doesn't escape the legal system, and everybody sees him as a crooked cop. Yadayadayada. That sort of thing, y'know. Happy endings are the norm and so overdone. A sad ending brings emotions about in the audience -- think: American Sniper, Fast & Furious 7, and Marley & Me. The utter sadness of the endings takes precedence over the positive elements. American Sniper, you're thinking, "Oh good, he finally came home and can settle down with his wife and kids...OH FUCK, HE GOT KILLED!!?? *tears*", Fast & Furious, "I mean everybody's so excited in the end, and they're all family, and that just makes Paul's death even more upsetting and replaces the positivity of the ending. *tears*" Marley & Me, "Marley died! *manly tears*" But it's whatever. Since it's your first movie, (I assume...Spielberg, is that you?) why not submit it to film festivals (Tribeca, etc.) to get your foot in the door? And I hope you have avid knowledge of Adobe produces, as they are the standard in the film editing. (Sony Vegas is nice, as well :p)
