Frédéric Tcheng focusing on Halston’s forgotten legacy, with the two-hour documentary ‘Halston’. He continues his dark traces of the designer’s personal life, excesses, and bad decisions, and asks, “Is it tougher to get on top or to stay on top?”

The iconic American fashion designer of the 70s, Roy Halston Frowick, created famous pieces like Jackie Kennedy’s pink pillbox hat worn at her husband’s inauguration ceremony in 1961 and the off-the-shoulder dress worn by Bianca Jagger on Studio 54’s dancefloor. Despite this, Halston never quite became a household name.

Now, writer and director Frédéric Tcheng, who brings to life movies like Dior and I, Valentino: The Last Emperor, Diana Vreeland: The Eye Has to Travel, sheds light on the designer’s unknown story with ‘Halston’ documentary.

“America’s first superstar designer, Halston rose to international fame in the 1970s, creating an empire and personifying the dramatic social and sexual revolution of the last century,” the official synopsis reads. ‘Halston’ is capturing the epic narrative of the life and time of legendary designer Roy Halston Frowick, who sets women free with their unstructured designs. The documentary, in which rare archival footage is expertly handled, includes interviews with Halston’s family, friends, Jacqueline Kennedy, Liza Minnelli, Andy Warhol and Iman.

The documentary will take place in theaters in this May.
