Limitless - Production

Production

Limitless is based on the 2001 novel The Dark Fields by Alan Glynn. The film is directed by Neil Burger and is based on a screenplay by Leslie Dixon, who had acquired rights to the source material. Dixon wrote the adapted screenplay for less than her normal cost in exchange for being made one of the film's producers. She and fellow producer Scott Kroopf approached Burger to direct the film, at the time titled The Dark Fields. For Burger, who had written and directed his previous three films, the collaboration was his first foray solely as director. With Universal Pictures developing the project, Shia LaBeouf was announced in April 2008 to be cast as the film's star.

The project eventually moved to development under Relativity Media and Sir Richard Branson's Virgin Produced with Universal distributing through Relativity's Rogue Pictures. By November 2009, actor Bradley Cooper replaced LaBeouf in the starring role. Robert De Niro was cast opposite Cooper by March 2010, and The Dark Fields began filming in Philadelphia the following May. Filming also took place in New York City. For a car chase scene filmed in Puerto Vallarta, filmmakers sought a luxury car. Italian carmaker Maserati provided two Maserati GranTurismo coupes free in "a guerrilla-style approach" to product placement. By December 2010, The Dark Fields was re-titled Limitless.
