James Wan (born 26 February 1977) is an Australian film producer, screenwriter and film director of Malaysian Chinese descent. He is widely known for directing the horror film Saw (2004) and creating Billy the puppet. Wan has also directed Dead Silence (2007), Death Sentence (2007), Insidious (2010), The Conjuring (2013) and Fast & Furious 7 (2015).

Before his success in the mainstream film industry, he made his first feature-length film, Stygian, with Shannon Young, which won “Best Guerrilla Film” at the Melbourne Underground Film Festival (MUFF) in 2000.

Prior to 2003, Wan and Leigh Whannell had begun writing a script based for a horror film, citing inspiration from their dreams and fears. Upon completing the script, Leigh and James had wanted to select an excerpt from their script, later to be known as Saw (2004), and film it to pitch their film to studios. With the help of Charlie Clouser, who had composed the score for the film, and a few stand-in actors, Leigh and James shot the film with relatively no budget. Leigh had decided to star in the film as well.

After the release of the full-length Saw (2004), the film was met with overwhelming success in the box office both domestically and internationally. The film ended up grossing 55 million dollars in America, and 48 million dollars in other countries, totaling over $103 million worldwide. This was over 100 million dollars profit, over 80 times the production budget. This green-lit the sequel Saw II (2005), and later the rest of the Saw franchise based on the yearly success of the previous installment. Since its inception, Saw (2004) has become the highest grossing horror franchise of all time worldwide in unadjusted dollars. In the United States only, Saw (2004) is the second highest grossing horror franchise, behind only the Friday the 13th (1980) films by a margin of $10 million.
