Lenn Kudrjawizkis family moved with him as a child from Leningrad (USSR) to East Berlin. At the age of four, Lenn auditioned on the stage with the Leningrad State Ballet. At five, he became enchanted with a violin that his father brought down from the attic of the family home. This was to play an important part in his life. Later he attended a secondary school for music in Berlin where he studied acting, voice, and violin. In Dresden he refined his skills on the violin and graduated with a Master of Arts in Music in 2003. In 1994 Lenn made his television debut as a teenager with the role of Wladimir in the film KATRIN UND WLADIMIR. Jean-Jacques Annaud's DUEL - ENEMY AT THE GATES followed, as well as Alain Gsponer's feature film KIKI & TIGER. From 2001 to 2006 Lenn was a series regular in the highly acclaimed RTL series ABSCHNITT 40. Since, he was performing in more than 50 TV and feature film productions, including POPE JOAN, THE COUNTERFEITERS - 2008 Oscar winner for best foreign-language film -, Paramount Pictures' JACK RYAN: SHADOW RECRUIT, directed by Kenneth Branagh and most recently THE TRANSPORTER REFUELED - written and produced by Luc Besson. Since 2016 Lenn is back as a detective in the KROATIEN KRIMI for ARD (national German Television).
Lenn was giving his directors debut in 2007 with the short film TODAY IS MY DAY. His second work as a director and writer was THANK YOU MR. PRESIDENT (2009), that successfully toured international festivals and has won the renowned award Murnaupreis.
In 2014, Lenn filmed his third short film BUSINESS AS USUAL - THE PROPHET FLIES, for which he received the Amnesty International Human Rights Award.
