Redline is a 2007 American independent racing action-thriller film. The film's plot is centered on a street racing circle funded by a group of multimillionaires who wager millions of dollars over their high-powered sports cars. It was written and produced by Daniel Sadek, who also used his own automobile collection in the film. The film title was borrowed from the original working title of the 2001 film, The Fast and the Furious. A critical and financial failure at the box office, the film is most notable for being funded by subprime loans issued by Sadek's company, Quick Loan Funding, which closed its doors in the wake of the subprime mortgage crisis. It was featured on the CNBC special House of Cards as an example of the excess of the pre-meltdown mortgage market in the United States.

Redline was released in North America on April 13, 2007.
