Michalina joined the project a relatively short time before we started filming, but we trusted her since we saw her for the first time. We had been looking for her for a long time. At the beginning it was difficult, but when we got clear with Michalina during the first week of shooting about the attitude and personality of the character, the rest came easily. Michalina simply immersed herself in Olga and became her. Her powers of concentration were incredible, she didn't talk to anyone, during breaks she prepared for the next shot, after shooting she left for the hotel, where she was alone, like Olga. For us this was important primarily because we could focus our attention on supporting characters who don't have as much space in the movie, and therefore had a more difficult time of it. We enjoyed working with Michalina. It's a real advantage for us when you don't have to explain every little thing to an actress. She understood us. She understood the character. We often dug deep into her with just a few sentences, words, or looks. It's important as an actor to be strong inside, or rather to conceal the emotions. They can then break out to the extreme.
