Rüdiger Böss, for over a decade one of the best-known and liked acquisitions executives in the international television business, is to join Constantin Film, Germany’s leading independent movie producer and distributor — responsible for the hugely successful “Resident Evil” franchise — and an increasingly important producer of international TV series.

Until last year, Böss served at ProSiebenSat.1 Media Se, one of Germany’s leading broadcast networks, as executive vice president of group content acquisitions and sales, a position he held for 11 years. He was responsible for the negotiations for and acquisitions of licensed movies and series for the entire media group.

As of November, Böss will be employed at Constantin Film as a producer of theatrical films, TV movies and TV series. He will also be joining the management team at Constantin Pictures, a subsidiary of Constantin Film Intl., and will be one of its managing directors.
