(1) In cases of doubt, anyone who undertakes to participate in the production of a film, in the event that they acquire a copyright in the cinematographic work, grants the producer of the film the exclusive right to use the cinematographic work, as well as translations and other cinematographic adaptations or transformations of the cinematographic work in all manner of uses. Section 31a (1) sentence 4 and 5 and (2) to (4) does not apply.
(2) Where the author of the cinematographic work grants the right of use designated in subsection (1) in advance to a third party, the author nevertheless always retains the right to grant this right to the producer of the film, either in limited or unlimited form.
(3) Copyrights in the works used in the production of the cinematographic work, such as a novel, screenplay and film music, remain unaffected.
(4) Subsections (1) and (2) apply accordingly in relation to the rights of cinematographic exploitation in photographs and photographic works produced in connection with the creation of a cinematographic work.
