Three days before his 40th birthday, Klaas Heufer-Umlauf returns from the summer break with his ProSieben show “Late Night Berlin” on Tuesday (September 19th, 11:15 p.m.). This time Klaas welcomes the musician and Oscar winner Jared Leto (51, “Dallas Buyers Club”).

“Together they are looking for the singer’s biggest fan,” ProSieben announced in advance. The big fan should be identified in the studio: “Who knows everything about his life? Who knows all the songs of his band Thirty Seconds To Mars in their sleep?” Heufer-Umlauf also gets a surprise guest – someone “whom the whole of Germany knows,” as the private broadcaster in Unterföhring near Munich put it.
