- Actor-Shared Background: Darren Criss shares Cunanan's mixed Filipino-American heritage.
- Disowned Adaptation: Versace's family, who had already denounced the source book for its rampant speculation like Cunanan having previously met Versace, were no kinder to the show.
- Fake Nationality: Édgar Ramírez, Penélope Cruz, and Ricky Martin —all playing real-life Italians here— are Venezuelan, Spanish, and Puerto Rican, respectively.
- Production Posse: Some of this show's cast is comprised of Ryan Murphy mainstays:
- Recycled Set: Jeff Trail's apartment is clearly the same exterior building used for the loft in New Girl. The A.V. Club took note of this and were unsettled about the tonal differences between both series.
- What Could Have Been: Lady Gaga was originally cast as Donatella Versace, but dropped early on due to a busy schedule and was replaced by Penélope Cruz.
