This is about the Bulgarian continuation to this film:

“We discussed what would be the most useful contribution of Bulgaria in the realization of this film, because this is the point of co-productions. In the film we have a Bulgarian costume designer - it is Geo Karl Pavlov, and the main make-up artist is Magdalena Boyadjieva. Ivan Andreev did the sound post-production. The sound was recorded on location by Veselin Zografov and Sofia Zhecheva. Christina Samsarova also helped in my team as an associate producer. I am very grateful because every member of the team is very important. All in all, I am very happy that my colleagues were very satisfied with the Bulgarian team and we are even currently planning to work on the director’s next feature-length project,” Katya Trichkova points out.

The project came about after a 2-year application process - not only in Bulgaria, but also in other European countries, including Denmark, Croatia, Slovenia and France.

‘We heard the word “no” much more often than “yes” - for the financing of the film, I mean,’ Trichkova explains.

The project itself came to her through Croatian producers Daniel Peck and Katerina Purpic, who are friends of Trichkova.

“I’ve known them for years and we share a common taste in cinema. We have tried several times to make joint productions and quite naturally they approached me with this short film project,” she says.

According to the producer, the second time they applied, they managed to get funding from Bulgaria. Subsequently, a French and then a Slovenian producer got involved, making filming possible.
