Prison Break

Stacy Keach (the Prison Warden) spent six months in a British prison and modeled his character after the man in charge at that institution.

It took 4.5 hours to apply the tattoo to Wentworth Miller on set.

Michael Scofield's tattoo was designed by tattoo artist Tom Berg. Berg was asked to work on the show by Brett Ratner after previously designing the tattoo for the character of Francis Dolarhyde in Ratner's film El dragón rojo (2002). Berg estimated that to get the tattoo done for real would take four years and would cost between fifteen and twenty thousand dollars.
