Tom Welling directed this episode.
In several episodes, the rainy Metropolis view that is shown is actually a scene from Batman Begins (2005). It's a view of The Narrows and Arkham Asylum with surrounding Gotham in the background. The scene can be found at the beginning of the 'Lighten Up' chapter.
This is the second episode Tom Welling has directed. His first was "Fragile".
Linda Lake has the same initials as four of the main characters: Lex Luthor, Lana Lang, Lois Lane and Lionel Luthor.
