Later, he worked with the Düsseldorfer Schauspielhaus, and played the role of Tybalt in Shakespeare's Romeo and Juliet in the Deutschen Schauspielhaus in Hamburg. His first memorable role in cinema was in 1991, in the film Das serbische M?dchen, where he played the role of the arrogant German boyfriend of the pregnant Serbian heroine. His big break was in 1995 as Peter, who fell in love with a man, in Joseph Vilsmaier's Schlafes Bruder. In the film Comedian Harmonists he played the singer Robert Biberti.

In 2008 Becker worked with the German band Schiller (band) (thus following in the footsteps of his stepfather Otto Sander), where Ben did spoken lyrics for the album Sehnsucht. One song is called "Nacht", a video of which can be seen on YouTube. The lyrics are a shortened version of a poem in German called Die Seele that is attributed to Lord Byron. It appears to be a translation of the Byron poem, "When coldness wraps this suffering clay" s:When coldness wraps this suffering clay from the collection, Hebrew Melodies. The identity of the translator/author of Die Seele is unknown although the text may be from "Lord Byrons Werke In sechs B?nden" translated by Otto Gildemeister, 3rd Volume, Fifth Edition, Berlin 1903 (pages 134-135).
