Jeremy Miliker was born in St. Johann im Pongau, Austria in 2008. At the age of seven, he went to a casting for Adrian Goiginger's autobiographical drama "Die beste aller Welten" and was promptly chosen for a leading role: Miliker plays the son of heroin-addicted woman who desperately tries to quit drugs. Before the premiere of "Die beste aller Welten" at the 2017 Berlin IFF, Miliker appeared in the Austrian TV comedy "Die Notlüge" (2016/17) alongside Josef Hader, Brigitte Hobmeier and Pia Hierzegger.

Miliker next appeared in the TV productions "Steirerkind" (DE/AT) and "Balanceakt" (TV).
