Marcelle Marais' filmmaking explores gender relations, primal human instincts, and social inequities, often centering the archetype of woman as witch through supernatural and occult ritual. Her work integrates strong, unapologetic female leads in psychological cinema, heavy metal, and live performance art, challenging male-dominated spaces in film and music.

A graduate of San Francisco Art Institute (BFA 2011), Marais studied with George Kuchar, blending cinematic magical surrealism with live performance art. She later continued her mentorship in time-based media with acclaimed performance artist Guillermo Gòmez-Peña.

Through her production company, TriTonia Films, Marais directs music videos for Bay Area and international bands, driven by a passion to elevate underground artists and strengthen the local music community. Her work spans music videos, live soundscapes, and experimental film, including TriTonia (2018), performed with synth noise quartet TriTonian Mass. She won the award for Best First-time Filmmaker at the 2025 Munich New Wave Short Film Festival for her film Shrieek. She has exhibited internationally.
