Amy, as it was billed, was said to explore "the enormous pressure a sensationalist public put on a young superstar when her problems began." Johanne Louise Schmidt was cast as Winehouse.
The singer, who earned acclaim for her 2007 album "Back to Black," battled drugs and alcohol during a very publicized downward spiral, which resulted in her death at the age of 26 in July 2011.
Winehouse also released the 2003 album "Frank." Her material ranged from R&B, pop-influenced songs like "Rehab," "F*ck Me Pumps" and "Stronger Than Me" to standards including "Someone to Watch Over Me," "There Is No Greater Love." She also recorded the jazz standard "Body and Soul" with Tony Bennett for his "Duets II" album.
