Markovics' mother worked as a clerk and his father was a bus driver. Markovics did not want to go into a professional career but wanted to become a stage actor, which his parents supported. However, he failed to pass the entry exam for the Max-Reinhardt-Seminar. He did not let this deter him from his dream and began performing at the Serapions Theater in Vienna. In 1987, he started working with the Wiener Ensemble. In 1991, he got his first part in the movie, "Hund und Katz" and in 1993, he played the part of the innkeeper in Paul Harather's tragic-comedy road movie "Indien".
Markovics remains a frequent stage actor, and in April 2010 played the non-singing role of Samiel in Counterfeiters-director Ruzowitzky's first opera production, Der Freischütz at Vienna's Theater an der Wien. He directed and wrote Atmen in 2011.
Personal life
Markovics is married to actress Stephanie Taussig. They have two children, Louis and Leonie, and reside in Vienna, Austria.
