In 2014, he published the book
Villa Ibsen, which deals with his famous family. The book received mixed reviews, particularly highlighting portraits of the author's grandparents Sigurd and Bergliot Ibsen as interesting. In the depiction of the great-grandparents, Bille adds little new and largely builds on older portrayals and popular perceptions of Ibsen, which have been criticized in recent historical Ibsen scholarship. Thus, the biography conveys myths about Henrik Ibsen's difficult childhood, conflict-ridden relationship with his father or
Knud Ibsen as a tyrannical alcoholic, myths that were refuted in
Jørgen Haave's book
Familien Ibsen [The Ibsen Family] (2017). Contrary to Bille's claims, Haave notes that Ibsen had a comfortable childhood, was pampered by his father and was an arrogant child with a strong patrician identity. ==Filmography==
