No one else was injured.
The armed man entered the Kinopolis Movie Theater in the early afternoon in the town of Viernheim and apparently fired a gun, police spokesman Bernd Hochstaedter told Nippon Television.
Police shot the suspect dead about three hours later, Hesse interior minister Peter Beuth said. It was not immediately clear what the assailant’s identity and motives were.
Viernheim is about 45 miles south of Frankfurt.
The movie theater is part of a large chain in Germany.
