Trivia: When Frank Castle is in the jail cell, he has nightmares and flashbacks to his family before and during their execution at the hands of the mafia. In one of the shots, his daughters can be seen wearing Spider-Man pajamas when squirting water guns at him. This is a homage to the Punisher's very first appearance in 1979's comic, The Amazing Spider-Man #129, in spite of the director's desire to distance the movie from the comics as much as possible.
