It should really be called "Letterbox person ID", since it's not just actors but also directors etc. that link in this way. 1Veertje (talk) 02:00, 17 February 2019 (UTC)[reply]

@1Veertje:As it is right now, both directors, screenwriters and composers have their own distinct formatter URL. --Trade (talk) 23:00, 16 February 2020 (UTC)[reply]
