After Wortmann's A-Levels he wanted to become a professional football player and started playing with Westfalia Herne and later SpVgg Erkenschwick in the German 3rd division.

After spending some time at the London Royal College of Art he finished his career successfully.

While studying, he worked as a taxi driver and actor, for example in the TV series Die glückliche Familie.

At every match he sat on the trainer's bench and, by order and for account of national team manager Jürgen Klinsmann, he prepared films which were later shown to the players in order to prepare them for an upcoming match.

The two-hour documentary film on the world cup, produced from over 100 hours of filming material, was presented to the Germany national football team on 14 August 2006 as a preview and premiered in cinemas on 5 December 2006 under the title Deutschland.

Wortmann is an active member of the German authors' national football team (Autonama).
