Lucas Gregorowicz was born in London in 1976 but mainly grew up in Bochum where he attended Westfälische Schauspielschule from 1996 to 2000. From 1997 on, he was a guest cast member at Schauspielhaus Bochum where he performed in Leander Haußmann"s 1999 production of Shakespeares "Much Ado about Nothing". After several appearances in TV series such as "Motorradcops", "Die Wache", and "Adelheid und ihre Mörder", Gregorowicz made his movie debut alongside Moritz Bleibtreu in Christian Zübert"s cannabis comedy "Lammbock". He then starred in Fatih Akin"s "Solino", in Vivian Naefe"s "So schnell du kannst", and in Sönke Wortmann"s "Das Wunder von Bern" ("The Miracle of Bern"). In "Cattolica", directed by Rudolph Jula, Gregorowicz played the hedonist Stefan whose life is turned upside down when he meets a stranger.

In the following years, Gregorowicz was regularly seen on TV and starred, for instance, as Jona in the ARD series "4 gegen Z" (2005 to 2007). Since his last role in movie in the drama "Sugar Orange" (2004), it took him until 2008 to return to the big screen in a leading role: In "Hardcover", Gregorowicz played a wirter, who turns to the milieu of small-time criminals to find inspiration for his next novel. The film was again directed by Christian Zübert.
