Kamarás was born and raised in Pécs, Hungary. His mother, Teodóra Uhrik, and his stepfather, Pál Lovas, were both ballet dancers, and much of his childhood was spent in theaters. When he was seven, the family acquired a recording of the 1980 BBC production of Hamlet starring Derek Jacobi as Hamlet and Patrick Stewart as Claudius. Kamarás fell in love with the role of Hamlet and by the time he was eight had learned Hamlet's monologues from the play off by heart. From 1991 to 1995, he studied at the Academy of Theatre and Film in Budapest.
