Martin Hrebeň played his first role as a 10-year-old in Martin Sulík's film Staccato. The role that made him famous was the embarrassed red-haired boy, the orphan in the film Freckled Max and the Ghosts and in the series Aunt. At the age of 13, he began performing at the LUDUS Theater. Despite his rich acting experience, he was not accepted to the conservatory because he did not master playing a musical instrument. He is no longer involved in acting.
