Miletić was one of the founders of the Zagreb film club in 1928.[2]
Miletić participated in an amateur film competition in Paris in 1933 with his Poslovi konzula Dorgena and received an award from Louis Lumière.[3] His 1937 film Šešir was the first Croatian movie filmed with sound.[3] In the Independent State of Croatia, Miletić filmed three cultural films for Germany's Tobis Film: Hrvatski kipari, Hrvatski seljački život and Agram, die Hauptstadt Kroatiens.[4] While all three films were originally thought lost, Daniel Rafaelić discovered Hrvatski seljački život in a Vienna film archive in 2004 and in 2008 discovered Agram, die Hauptstadt Kroatiens in a German film archive.[4]
In 1967 he received the Vladimir Nazor Award for lifetime achievement in film arts.[7] The Oktavijan Award is awarded annually by the Croatian Association of Film Critics as part of the Days of Croatian Film.[8]
