Blazej started his career writing copy and cutting trailers for films and TV shows at HBO Poland.
His first script, a contained thriller Dog Night Brother, went on to become one of the Black List Top 10 Thrillers. Writing in both English and Polish, he consulted a biopic Sztuka Kochania (highest grossing Polish film in 2017) and Coldest Play, a spy thriller set in the 1950’s.
He is best known for writing SF shorts Legendy Polskie, a YouTube sensation with a big fanbase, directed by Oscar-nom Tomek Baginski.
His new scripts include a TOEI Animation's adaptation of seminal manga Saint Seiya and SONY/AXN series UltraViolet directed by Jan Komasa, where Blazej worked alongside Chris Barbour (Criminal Minds), Barry Josephson (Bones) and Wendy West (Dexter).
