There are two of my films which can be called "advertisements".
They are both non-commercial.

Then: "Waiting room"

(Original title: "Poczekalnia", 2008)

I made it with my friend for "Lublin is coming" contest for video advertisement of City of Lublin. The film was applauded by audience, which I was proud of.

Now: "Hype-paté"

(Original title: "Zajepasztet", 2009)

This is my most successful film. It has over 1M views on YouTube, and dozens of remakes has been made. It is an example of power of web advertisement, even if the product is fictitious.
