Marc Forster (born January 27, 1969(1969-01-27)) is a German-Swiss filmmaker and screenwriter, known for films such as Monster's Ball, Finding Neverland, Stranger than Fiction, and Quantum of Solace.

Marc Forster was born in Au (today Illertissen), in the Neu-Ulm district of Bavaria, as the son of a German doctor and a Swiss architect and grew up in Davos, a winter resort in eastern Switzerland. When still very young, his family moved to Switzerland after learning they were blacklisted by the Baader-Meinhoff group, the predecessor to the German terrorist organisation Red Army Faction (RAF). The first film he saw in a cinema was Apocalypse Now by Francis Ford Coppola, when he was 12. He was so excited about it, that from that time on he didn't hesitate when asked about his dream job: "Director".

In 1990, when he was 20 years old, Forster moved to New York, in the United States. For the next three years, he attended New York University's film school, making several documentary films. In 1995, he moved to Hollywood and shot an experimental low budget film ($10,000) called Loungers, which won the Slamdance Audience Award. Forster's first motion picture was the psychological drama Everything Put Together, which was nominated for the Grand Jury Prize at the Sundance Film Festival.
