The scar under Jeffrey Donovan's left eye is written into the show as something Michael's abusive father gave him "to remember him."
Lead actor Jeffrey Donovan said in a June 2021 interview that he initially had harsh words about the show while he was filming its seven seasons. After awhile it felt like he was trapped in prison because the show took up so much of his life. Even during the off season, he was always exercising and training to be ready to start the next season. It was exhausting because it seemed like it would never end. But when the series did finally end, he said a year later he just cried wishing he had that back. In retrospect, he was very grateful for it because it changed his career.
Through the series, when aerial shots of Michael's Dodge Charger driving throughout Miami are shown, a Miami Police cruiser can usually be seen a few car lengths behind, providing escort for filming purposes.
Michael's sunglasses are made by Oliver Peoples, and are named Victory. They were custom made for the series, and have polycarbonate "safety" lenses.
The building that is supposed to be Michael's loft is located on NW 7th Avenue, between NW 6th Street and NW 5th Street (528 NW 7th Avenue) Miami, Florida 33136. It can be found in Google Maps at 25.779033,-80.20706.
Matt Nix: The series creator has an uncredited cameo in the opening credits of every episode. Nix is the guy who says, "We got a burn notice on you. You're blacklisted."
