In UFO: It Is Here, Dennis played Leo Best, one of the final year film students who end up in a dark forest at night by accident, only to witness signs indicating that a harrowing crime has taken place. Instead of trying to escape, the curious men and women embark on the mighty task of following the ghastly trails.
In Traumfabrik, Dennis played Emil Hellberg, the love-struck protagonist’s brother. Having witnessed how the building of the Berlin Wall tore apart Alex (Ken Duken), and his girlfriend, Milou (Emilia Schüle), Emil pledges to help out the rebellious duo. They come up with a part-genius, part-impossible plan which allows them to see each other once again — regardless of the severe geo-political restrictions.
