Mammoth is a 2009 Swedish romantic drama film directed by Lukas Moodysson, about a successful New York couple experiencing conditions related to modern day globalization. The couple is played by Gael García Bernal and Michelle Williams, in the roles of Leo and Ellen Vidales. The title superficially refers to the mammoth ivory pen Leo receives as a gift. In addition it relates loosely to a quote from one of Moodysson's poetry collections: "Our Savior buried like a Mammoth."

Karl Fredrik Lukas Moodysson is a Swedish novelist, short story writer and film director.

He has since directed a string of films with different styles and public appeal, as well as continued to write both poetry and novels. In 2007, The Guardian ranked Moodysson eleventh in its list of the world’s best directors, describing his directorial style as “heartfelt and uncompromising.”
