Robert Stadlober was born in Friesach in the Austrian province of Carinthia, and grew up in Puchfeld in the Steiermark (Austria) and in Berlin (Germany).

His largest success is playing the main role as Benjamin Lebert, a partially disabled teenager at a boarding school, in the film Crazy (2000). Later, he starred in Summer Storm (2004), a gay coming-of-age story set at a rowing summer-camp. Although The Advocate has claimed that he is bisexual,^[1] Stadtlober himself objects to such labelling, saying that he's just had some homosexual experiences and that this is normal.^[2]

He was awarded the "best young actor" award at the Montreal World Film Festival in 2004 for his portrayal in Summer Storm.
