After about 20 years of working and living in the United States, Verhoeven returned to the Netherlands for the shooting of a new film. Together with his screenwriter Gerard Soeteman, Verhoeven made Black Book (2006). The director was hailed by the host of the Netherlands Film Festival with the words "The return of a hero." Black Book eventually won six Golden Calves at this festival, including Best Director. When the shooting of Black Book was delayed due to financial issues, there was speculation about a new production. The film Beast of Bataan had been announced, but once the shooting for Black Book resumed, the other film was never realized. Since his return to European cinema in 2006 with Black Book, Verhoeven has been connected to a large number of projects, but for the moment none of them has come to fruition. Some of those titles were produced with other directors at the helm, such as The Paperboy.  Finally, in a rather unexpected twist, Verhoeven followed Black Book by directing a movie in French: Elle, an adaptation of a novel by Philippe Djian. The film by Verhoeven, a psycho-thriller where Isabelle Huppert plays a rape victim, was selected in the Official Competition at the Cannes International Film Festival, where it obtained very favourable reviews.  Verhoeven has been a knight in the Order of the Netherlands Lion since 2007. In December 2016 it was announced that Verhoeven would be the President of the Jury for the 67th Berlin International Film Festival, scheduled to take place in February 2017.  In April 2017 his next French film titled Blessed Virgin was announced, to start filming in August of the same year. It is a biographical film about the life of Benedetta Carlini, which will be portrayed by Elle co-star Virginie Efira, and is an adaptation of the non-fiction book Immodest Acts - The life of a lesbian nun in Renaissance Italy by Judith C. Brown.
