Eric Rentmeister received his diploma in acting, singing and dance from the Folkwang Hochschule Essen in 2004 and was directly casted by Vincent Paterson (known as the choreographer of Madonna, Michael Jackson and of films such as "Dancer in the Dark", "Evita") for the 'Master of Ceremonies' in the production of "Cabaret" at the Bar Jeder Vernunft, Berlin. He played this part more than 400 times, but in this character he also hosted galas with Ute Lemper and Max Raabe. This was followed by Europe-wide musical engagements, for example riff in "West Side Story", Harry Frommermann in "Comedian Harmonists", the Stollentroll in "Die 13 ½ Leben des Käpt'n Blaubär", Lord Farquaad in "Shrek" and the title role in Mozart's "Der Schauspieldirektor". Currently he plays the Miss Understanding in the musical "Priscilla - Queen of the Desert" at the Gärtnerplatztheater Munich.
Eric Rentmeister works as a freelance actor, among others at the Consol Theater Gelsenkirchen. There he was involved in the development of the play "Eagle calling Hawk", which won the jury and audience award at the WESTWIND Festival in Cologne in 2011 followed by invitations to Wales, Serbia and Croatia. He is currently performing at the Consol Theater in the world premiere of Roland Schimmelpfennig's "The Bee in the Head" and the play development "The Flat Rabbit".
In 2009 he choreographed the musical "Evita" at the Theater Dortmund (director: Stefan Huber). In 2011 the same director asked him to choreograph the Beatles tribute "White!" at the Theater Heilbronn, where he has been working as a choreographer ever since, among others for the "Rocky Horror Show", "Spring Awakening" and this season for "Born to Be Wild?".
Since 2009 Eric is giving courses or leading academies for the Deutsche SchülerAkademie. He is a lecturer for song interpretation and audition training at the Hochschule Osnabrück in the Musical Theatre programme, taught musical staging at the Folkwang University of Arts Essen and supervised projects at the University of Hildesheim.
