My Missions

Historical advising

I ADVISE AND CONSULT ON CREATIVE PRODUCTIONS OF ALL TYPES. I OFFER A WIDE RANGE OF SERVICES AT ALL STAGES OF A PROJECT’S EVOLUTION, FROM RESEARCH AND STORY CONCEPTION AND ON SET-ADVISING AND POST-PRODUCTION AUTHENTICITY REVIEWS.

DEVELOPMENT: RESEARCH AND CONSULTING FOR STORY DEVELOPMENT

I provide research consulting when a project is in the crucial developmental stage. I understand the creative process and support writers and creators by digging up rich resources and new leads, tapping into sources behind academic paywalls, and fueling ideas for story threads, characters, scenes, and even sensory experience. I answer specific research questions but can also provide a holistic sense of time, place, people, and events. For example : I have helped cast members on The Last Duel to dive into 14th century France. How a noble of the time should behave at the table, how he would pray and what with (working with the props team), how he would behave in public, how he would bow to a woman or pay respect to his lord, how one would count their fingers ….
 
I also help creators go beyond optioned material by drawing from new sources on the person or event, combing through additional documents and sources to suggest the most powerful moments and memorable characters that might be included in the production. I enable writers and producers to exercise creative license without sacrificing accuracy or authenticity.
 

I can provide a comprehensive timeline, dossier, or analysis of the real-life events and figures, fact check any situation or individual, or suggest related story threads and characters. I QUICKLY scour all relevant books, memoirs, photographs, archival documents.
