In 2003, Sucsy was inspired to write and direct a narrative feature film about the famous true story of Jackie O's eccentric relatives "Big Edie" Bouvier Beale and "Little Edie" Bouvier Beale called Grey Gardens after viewing the well-known documentary of the same name. The day after he first watched the documentary, Sucsy embarked on what was to become a six-year process to get Grey Gardens made. He used primary sources including Little Edie's personal correspondence, private journals, and poetry as well as interviews with family members and friends as the basis of his original script which traced the Beales' tragic descent from riches to rags over some forty years. With Drew Barrymore and Jessica Lange attached to star as the reclusive mother-daughter duo, the project made its way to HBO who, in 2006, announced that Grey Gardens was moving into production with Sucsy as its Director. Principal photography on Grey Gardens began in October 2007, and it debuted on HBO in April 2009 to great acclaim from critics and audiences, both new and old to the Grey Gardens phenomenon.
