A spec commercial, real or fake, is one you do for free to prove you can make a spot. The big trick is to make your spec spot look not like a spec spot. If it looks spec, it will suck, defeating the very purpose of doing it. Now, every director entering the commercial world needs a spec spot. I’ve seen tons of them, many riddled with mistakes that give away the fact they’re not real. Heed my wisdom, and you’ll succeed.
Here is a spec I made years ago with a script from real DDB Chicago. Almost went to the Superbowl, but almost doesn’t count. It did get me tons of work.
And I still want to hear about your passion project!
