Why the Association Occurs
Listeners and viewers may link John Lithgow to Harry Potter due to several factors: his son, Ian Lithgow, worked in entertainment but not on Harry Potter; shared genre work in elevated fantasy or prestige drama; and algorithmic suggestions that group high‑profile actors across unrelated franchises. These patterns can create an impression of connection that casting records do not support.

These materials provide durable evidence that remains useful as catalog titles age and new fans search historical overlaps.
