Gossip Girl, S02E19
Maureen, Tripp's fiancee, approaching Vanessa with graceful superiority, giving a lecture on blue blood (ref. 14:01), reminded me of Ready or Not (2019): in the wedding scene, the mother-in-law gave an impressively similar speech to the bride (ref. 07:55).
All I Wanna Do (1998)
Then overall character structure reminded me of Scent of a Woman (1992).
