After completing his degree from Marmara University's Business Department, Ünalmış sought a shift in his career. Drawn to the arts, he enrolled at Akademi Istanbul for acting lessons. It was during this time that he began to showcase his versatility, working on projects like 'Hayat Bağları' and 'Sınırlı Aşk'. It didn’t take long for him to transition from television series to movies, with roles in films such as 'Deli Duran' and 'Sen Ne Dilersen'.
However, his major break came with the film 'Güneşi Gördüm', directed by Mahsun Kırmızıgül, which widened his fan base substantially. Ünalmış later featured in another of Kırmızıgül's works, 'New York'ta Beş Minare'.
