- During the filming of the bridge hostage exchange scene in 1.02 Lost & Found, Barnett slipped and badly injured his right shoulder. The in-series trend of Dirk getting injured on his right side might have been influenced by that, or is just an amusing coincidence.
- Barnett coined the term "Dirktectives" for fans of the series.
