I had some concerns with making a very Polish picture, impossible [for audiences] to understand without knowing the poem. When the movie was accepted into the festival in Berlin, I thought, "Well, OK, but after all they also had a romantic movement [in literature]." I breathed a sigh of relief when I got an enthusiastic e-mail from the organizers of the festival in Tehran. They understood my film, people brought up in a different culture, different literary and religious traditions. Then I realized how universal the feeling of nostalgia is.The film combines elements of oil painting and three-dimensional space while at the same time expressing classical animation with effects and computer animation. The unique aesthetics of images is achieved by using the latest technologies, the effect of "brush strokes". Work on the film - from concept to completion - took seven years. The film was produced at the Human Ark computer graphics studio in Warsaw.
