From big and bold characters to small and understated ones, the enduring quality in Sebastian's work is finding authentic and truthful humanity in every role. Sebastian has been described as having "the ability to maintain striking presence and poignant subtlety at once" (Ross Larkin, Theatre Press). It's no accident that he's spent his career playing intense, often flawed characters on both stage and screen, from soldiers and cops, to goons and misfits, to queer activists and war criminals. His credits include productions from HBO ("The Pacific"), Warner Bros/Bad Robot ("Fringe"), Fremantle Media ("Wentworth") and Seven Studios ("Secret Bridesmaids' Business"), in addition to extensive independent film, web series and theatre work. Sebastian's latest appearance was in the feature film "In Corpore" (directed by Sarah Jayne & Ivan Malekin), currently streaming on Amazon Prime.
