The letgo Commercializer is the first and only way to create a million-dollar Hollywood commercial for someone's secondhand listing, without the inconvenience of spending a million dollars, and actually going to Hollywood.

Once they’ve listed an item for sale in the app, sellers simply choose from one of four glossy ad styles to have a completely customized commercial created, which incorporates all the details of their item listing.

Everything from the item image, the title, description, price, location and even the seller’s name are neatly and seamlessly woven into the action to create a funny shareable commercial.

Sellers can choose from an epic ’80s action movie trailer starring Dolph Lundgren, a male enhancement pharmaceutical ad, a home shopping segment and a very serious perfume spot.

Each film is carefully crafted to celebrate the brilliance of the seller’s item, regardless of what it actually is.

The four commercial styles were chosen to be instantly recognizable to the American market, but also allow virtually any product to be the hero of the spot, regardless of what it is.

The listing details are weaved into the action in a number of different ways, but always stay true to the nature of the commercial style.

A number of techniques including 3D motion tracking, rotoscoping, frame blending, motion blur, and dynamic audio are used to ensure the imagery and details are seamlessly integrated into the finished commercial.

Once rendered, the commercial can be easily shared or broadcast in any way the seller sees fit. Interested buyers who see the ad (on Facebook, Twitter, etc.) can click through and talk directly to the seller to start negotiations.

At the time of entry The letgo Commercializer has been live for just one week. In that time with $0 spent in media, there have been over 100,000 completely unique commercials created and shared by letgo sellers.

With increasing momentum, on the actual day of submission to Cannes there were 35,000 unique commercials created.

In addition to helping the sellers actually sell their items brand sentiment went through the roof. Sellers (who would never have shared their listing) began playing along, explaining to their friends on social media how they managed to afford the glossy commercial for their $10 item.

And Dolph Lundgren became the first man in history to star in 50,000 commercials, for 50,000 completely different products.
