- Development Hell: There were talks about a sequel in 2009 and 2012, and nothing has emerged since.
- Fake American: Eddie Marsan (Red) is British.
- No Stunt Double: Daeg Faerch did all his own stunts.
- What Could Have Been:
- Ben Affleck, George Clooney, Leonardo DiCaprio, Matt Damon, and Dave Chappelle were considered for the titular role before the casting of Will Smith.
- Michael Mann and Tony Scott were considered to direct the film before Peter Berg was hired.
- The film evolved out of a much more adult script called "Tonight, He Comes", which was known mostly for its concept of a superhero who can't have sex because his ejaculations blow his lovers up (an argument first proposed in Man of Steel, Women of Kleenex). A comedic scene along those lines was included in the extended edition of the film, with Hancock telling the woman to move away before, well...
