Biopic of entrepreneur Joy Mangano (Jennifer Lawrence), a divorced mother of two who risks her life's savings to produce and market her invention, the Miracle Mop. Joy faces opposition from her dysfunctional family, including her father Rudy (Robert De Niro), as they meddle in her burgeoning business. But when the head of the newly founded QVC network (Bradley Cooper) gives her a chance to sell her product on live TV, the Miracle Mop becomes a household name. The success of that invention later leads to a home-shopping empire and Joy's ascension to the matriarch of her extended family. David O. Russell directed this briskly paced comedy-drama, with Diane Ladd, Virginia Madsen, Isabella Rossellini, and Elisabeth R?hm co-starring.
