Actor Muzi Mthabela has officially left Isibaya for greener pastures, but has shot down speculation that he's set to play the role of Shaka Zulu in an upcoming TV series.

The highly-anticipated Game of Thrones-style series based on Shaka's life, Shaka Illembe, is currently in production, with reports linking the star to the lead role as the Zulu king.

The timing may be good, but Muzi told TshisaLIVE that it was not the project for which  he had left Isibaya.
