Trivia: Serial Experiments Lain
- Hey, It's That Voice!: In the Spanish dub, Lain is Motoko Aoyama, Yasuo is Jet Black, and Alice and Reika are respectively Sayaka Miki and Madoka Kaname.
- Keep Circulating the Tapes: The original box set was out of print for many years, but a new combined Blu-ray box set was released in late 2012.
- Name's the Same: This series is about Lain Iwakura, not Lain Claes, protagonist of vulgar RPG Maker title Lain's Horrible Adventure, though this series is the subject of a gag in that one.
- The Wiki Rule:
- Word of God: Mika actually tried to delve into the wired like Lain, and got "stuck". After that her mind is literally gone and her brainless body is left for the rest of the series.
