Early Life and Education

Sofie Lassen-Kahlke is now at the age of 46, and was born on July 18, 1979, in Copenhagen. She is the daughter of lawyer Niels Kahlke and jurist Nina Lassen, and she has a younger sister, Ditte Lassen-Kahlke. During early childhood, she lived in Blovstrød in North Zealand.

She attended Tranegårdskolen and later Hellerup Gymnasium. In 1998, she began studying law at the University of Copenhagen and kept the degree path going alongside acting work for many years. She completed the program in 2015, graduating as cand.jur., with her final thesis work noted publicly as focusing on media law.

Personal Life

Sofie Lassen-Kahlke married Hans Poul Petersen on August 25, 2012, in Garnisons Church in Copenhagen. Their families had known each other for years through shared time on Fanø, and the relationship became public after they got together in 2011. The couple have three children: a son, Alfred (born January 2011), and two daughters, Agnes (born May 2014) and Liva (born September 2019).

Career

Sofie Lassen-Kahlke’s career began with family film and television roles and quickly moved into a level of visibility that many Danish performers only reach later. After early appearances, she became a major youth-film lead with Kærlighed ved første hik (1999), playing Anja opposite Robert Hansen.

The success of the film generated a continuing storyline of sequels that repeatedly brought her back to the same character across the 2000s, including Anja & Viktor (2001), Anja efter Viktor (2003), Anja og Viktor – Brændende kærlighed (2007), and Anja & Viktor – i medgang og modgang (2008).

At the same time, she stayed active in television, including roles in well-known Danish Christmas series such as Krummernes jul and Brødrene Mortensens jul, projects that often broaden a performer’s reach across age groups.

She later took on a central part in the drama series 2900 Happiness, expanding her profile beyond youth-oriented titles and into prime-time serial storytelling.

Her screen work continued with a mix of comedy, family films, and drama, including titles such as Familien Gregersen, Far til fire – gi’r aldrig op!, Pistoleros, and later features like Kufferten and Månebrand. She has also done voice work, including a Danish-language role connected to Teenage Mutant Ninja Turtles.

One of the more distinctive parts of her professional story is that she kept an academic track running in parallel. While continuing acting work, she completed a full law degree and later used that expertise as part of her public identity, which becomes especially relevant in her fiction writing where a lawyer is the central character in a crime series.

In 2017, she entered the entertainment competition Vild med dans (season 14) with professional partner Michael Olesen and won the season, adding a non-acting mainstream television success to her résumé.

From 2021 onward, she expanded into publishing. She debuted as an author with Ramt – 39 historier om at fylde 40 and followed it with the crime novel Adams arv, launching the series Et Ursula Madsen-mysterium, later continued with Hermans hævn.
