Alarm für Cobra 11 – Die Autobahnpolizei

Cobra11 is a German television action-series about a highway police duo in and around Berlin, later North-West Germany.

The original cast featured Johannes Brandrup as Frank Stolte and Rainer Strecker as Ingo Fischer. Strecker left the series just two episodes later and his replacement became Erdoğan Atalay as Semir Gerkhan.

Brandrup quit the series at the end of Season 1. The television network RTL, which carries the series, contracted Mark Keller as André Fux in his place. Keller left the series at the end of Season 3 and was replaced by René Steinke as Tom Kranich. He played the role between the seasons 4–6, then decided to quit to try other roles.

Atalay's new partner became Christian Oliver as Jan Richter in Seasons 7–8. When he left the series to build his career in the US, RTL turned to Steinke, who agreed to return at the beginning of Season 9. However, Steinke decided not to renew his contract, and left the series again at the end of Season 10. His replacement is actor Gedeon Burkhard as Chris Ritter. Burkhard is best known as Alexander Brandtner in another Austrian-German police show, Inspector Rex.

In season 13 Burkhard was replaced by Tom Beck as Ben Jäger. In 2013 Mark Keller returned for one 90 minute Pilot episode. In season 19 Beck was replaced by Vinzenz Kiefer as Alex Brandt, the new partner for Semir.

Alex Brandt will be replaced after 2 years by Daniel Roesner, Roesner’s episodes start with the 20th anniversary of the series in 2016.

Roesner is already known to Cobra 11 audiences for playing Tacho, whom we first met in 2010 while at the police academy. His character, along with Axel Stein’s Turbo, was so popular that he was brought back for a second guest spot in 2011, and Action Concept, the makers of the series, attempted a TV pilot called Turbo und Tacho, where it is revealed that his full name is Andreas Tachinski.
Roesner won’t be playing Tachinski this time; instead, after a haircut and a new wardrobe, he’ll be playing a cop called Paul Renner.

Paul Renner, now played by Daniel Roesner (known before as the man who preciously played Andreas "Tacho" Tachinski), was a younger acquaintance to Semir and is currently a good friend of his. When he joined the police force, Renner was awe-filled when he finds out that Semir works at the same precinct he arrived at, and they quickly become partners in the following cases. Renner is ambitious, youthful, and like Semir, can crack some humorous jokes whenever he can.

Further information of Paul Renner is yet to be revealed when season 39 of the series airs in Spring 2016.
