As Seen On Tv (2001)

Alexander is a talk show host on TV and a partying bachelor privately with an awful love life even though he dreams of settling down. One day his old friend Ralf brings him a manuscript for a book that he can't get published and asks Alexander to put his name on it for some more publicity. Alexander agrees without reading and finds himself in trouble when the book comes out and the views expressed in it are opposite to his own.
