Alexander is a 2004 epic film, based on the life of Alexander the Great. It was directed by Oliver Stone, with Colin Farrell in the title role.
The film is based mostly on the book Alexander the Great, written in the 1970s by historian Robin Lane Fox, who gave up his screen credit in return for being allowed to take part in the epic cavalry charge during the film's recreation of the Battle of Gaugamela.

The film was critically derided upon its release and failed at the American box office. It grossed only US$34 million domestically, while costing $155 million to produce. However, it did better internationally in recovering its losses, grossing a total of $132 million in overseas revenue.
