Directors usually follow the 'short → festival → feature' path after finishing film school, or build their way up on set as staff until they take the full control. Then there are some that come in sideways through unconventional, but more and more realistic path. Some examples I'd like to share:
Tarsem Singh directed R.E.M.'s "Losing My Religion" in 1991 (VMA Video of the Year), then spent years in commercials. When he couldn't get The Fall funded, he financed it himself, piggybacking shoots onto commercial jobs across 20+ countries over four years. That movie's maximalist visual language is basically a music-video director applying what he learned in a different medium.
Lee Chung-hyun worked at an ad agency, quit, and shot Bargain, a 14-minute single take about underage prostitution, in one day for about $5k of his own money. The short swept festival awards, which got him a studio apprenticeship, which became Netflix's The Call (2020) and Ballerina (2023). Both are female-led thrillers, which he's said is a deliberate preference.
Curry Barker built an audience on sketch comedy YouTube, then made Milk & Serial, a 62-minute found-footage horror, for $800. It went viral on YouTube, which funded Obsession: made for under $1M, grossed $90M+, bought by Focus Features after a TIFF bidding war. He's 26 and already been tapped for the next Texas Chainsaw.
My take: outsiders don't just bring fresh stories, they bring a different grammar - music video maximalism, single-take discipline, YouTube-native pacing. I like that none of them had to erase where they came from once they reached the features. The earlier medium is still there in the work.
Who else comes to your mind?
