2nd Class on the RMS Titanic?

[alphaboi867]

Every Titanic movie I've seen focuses on 2 sets of characters; 1st class passengers and 3rd class passengers. Sometimes the crew gets focus too. I can't recall ever seeing a movie that had 2nd class passengers as characters. I understand why 1st & 3rd gets attention because of the huge contrast in wow they were treated and survival rates, but are there any movies that include a 2nd class subplot or characters?
