While the movie was developping, Vince Vaughn was oactually cast as Bobby and Owen Wilson was originally cast as Stig. This later changed…
Actresses Ellen Pompeo and Marisa Tomei (photo below) were both proposed for the role of Deb, but did not make it.
This film is a typical example of action comedy. Directed by Icelandic director Baltasar Kormákur, it features Denzel Washington and Mark Wahlberg as the lead comedic duo.
This film is actually based on a comic series, also called “2 Guns”, created by Steven Grant.
Curiously, the movie trailer has The Dead Weather's 2010 soundtrack called ‘Die by the Drop’. This song was also used before in another Baltasar Kormákur trailer (‘Contraband’), which also starred Mark Wahlberg.
The film’s “southern” theme is largely present because most of the filming took place in New Orleans, Louisiana and areas around New Mexico.
Many directors were proposed, including Doug Liman, Antoine Fuqua, Pierre Morel and Martin Campbell.
