Born in Kiev, Ukraine (at the time still the Communist Soviet Union) to Irene, a concert pianist and Roman, a handcrafting bookbinder who secretly dreamed of becoming a stage actor, Juliette was surrounded by a profound love of the arts and literature from an early age. In 1986, the world’s worst nuclear disaster, Chernobyl, happened. The city of Kiev, just 30 miles from the site, was in a panic and all the children were being sent away to the south to escape severe contamination. Juliette was sent alone to Moldavia while her parents used the opportunity to try to escape the Communist regime. They appealed to the American government and the JCC community. To their good fortune they were granted permission to leave the country, (with the status of refugees) but not before spending a year in quarantine camps in Europe. Six months later, Juliette was whisked away by her parents on a train, and headed to Vienna, Austria. Then to Rome, before getting on a plane to Chicago, now 1988, where a volunteer Jewish family had sponsored their visa, allowing them to claim asylum and receive a Green card upon arrival, now being citizens of no country. This was as far as her parents could take her, they said, it was up to her to make something with her life in this now new and strange country.

Juliette danced classical ballet and played the piano through her childhood. As a teenager she began to perform at improv cafes that are sprinkled all over Chicago’s streets. "It was like play time," she recalls, "I could just pretend do be anyone, and being an only child, I lived inside my head most of my life anyhow."

Juliette graduated high school early, anxious to start her life independently, and moved to Miami to become a model. She dreamed to travel and her unending tenacity convinced Elite Modeling Agency to send her to Milan. She spent eight months there, and moved onto Paris where her discovery of acting was about to begin. She spent the next two years studying acting in Europe doing workshops in Paris, Amsterdam, and Hamburg.

In 2000, Juliette was ready for New York. She did not have any contacts there and the following two years were spent swimming upstream. While in New York, along with a handful of people she met along the way, Juliette formed a theater group. Using mostly original material with names like, "Rembrandt’s Eyes", "The Fallen Apple", and "Just One Dance" the troop rented rehearsal spaces and put on shows at $3 per ticket to cover their overhead. "We just wanted to feel like we were expressing ourselves, that people actually listened. It made us feel like nothing else more important then self expression."

Then September 11th happened. "That is when it all changed for me," she recalls, "I needed to focus, and choose a direction." And so, with that she packed up her life in the City and moved west. Los Angeles seemed to have welcomed her quite quickly, fore she landed parts on Fox’s 24 and NBC’s Law and Order. Then, an opportunity crossed her path. A film called This Girls Life with James Woods attached was looking for their lead actress. Director, producer and writer Ash (who is famous for discovering such personalities as Lucy Liu, Mischa Barton, and Angelina Jolie) and Muse Productions were looking for a A-list celebrity for the leading role to carry the film, but Juliette proved that the part was hers’ and won the role. "I’ve never seen this female perspective told before with such an honest, original, and intelligent voice," says Marquis, who plays the controversial role of an international porn star. "It is just not a stereotype of anything one might assume…it is real and refreshing." James Woods, Rosario Dawson, Kip Pardue and Michael Rapapaport co-star. The film brought her the attention of numerous critics, such as Roger Ebert’s "it’s of historical value, because it centers on the first performance of an actress who is going to be a big star." Screen International’s "…Marquis is the epitome of a movie goddess exuding as much intelligence as sex appeal." Variety’s "proves to be much more then a physical knockout." She went on to win Best Newcomer Award at the Vegas Film Festival, and a Best Actress Award at the MIFF Film Festival Internationale di Milano 2005.

Following post production, Juliette was handed a script called Hockey Mom, directed by Kari Scotland (L-Word, Liberty Stands Still). Juliette opted for the role of the street kid, hockey goalie. The high heels of her last role, she traded for a pair of ice hockey skates and trained for two months to play the game. Filming in Canada’s Calgary, the heart of the hockey capital, Juliette spent two more months working with real women Olympic players, loving every minute of it. Jessalyn Gilsig, Margot Kidder, Jason Priestley co-star.

Then came other roles. Each quite different from the next. The key for her is to play dynamic, complex characters, that have a point of view. This attitude brought her together with Scott Dacko, and The Insurgents project began. Filmed in New York, this is a story of some very particular points of view, all of which are relevant to our time and events at present. This project had a message, one that needed to be stated bluntly.

Juliette is in the words of another critic, "if she is not a star within the next five years, then you can judge me all you want."
