Prison Break

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

Wentworth Miller was a last minute casting choice. He started filming about a week after auditioning/being cast.

Nadine Velazquez played Maricruz Delgado in the pilot but was unable to appear in the series as she had signed on to appear in Me llamo Earl (2005) before the show was commissioned. She was replaced by Camille Guaty.
