Upon its release in cinemas in Poland, it was the number one movie for three weeks.
One of the photographs in the golden tree is of Yukio Mishima, the Japanese author who famously committed suicide by seppuku.
The names of several real teenagers who had committed suicide are included and easy to find during the Facebook sequences, including: Asher Brown; Deikitsen Wolfram Lupus; and Tyler Clementi (who was a university student).
