could a 'legacy sequel' be done?
imagine a sequel titled 'Titanic: Legacy' starring Kate Winslet as she is now at 50ish (so set like 25y later in late 1930s).. She has an estranged son (Dane Dehann), and Billy Zane is trying to track her down. also thered be support from surving characters like Kathy Bates, Ioan Gruffyd and a bunch of new actors (former A listers currently languishing in stream movies/series looking to be in a big theatre movie again e.g Julia Roberts, Catherine Zeta Jones, Jude Law, Ed Norton etc, dependable franchise names: Hugo Weaving, Ian McKellan, Brendan Fraser etc , and obviously various Downton Abbey actors)
at some point there'd be flashback scenes to Titanic (filmed new with deaged Kate/Leo - not neccsary for actual Leo to appear though) , and maybe the film would end on top a skyscraper like King Kong (Cal vs Rose, her line about how Cal possibly died in the crash of '29 just a throwaway bs)
written by committee and directed by some other random B/C list director studio hire (Justin Lin, Jonathon Mostow, Andy Muschietti etc) but Cameron giving it his blessing (and exec producer/cowriter credit a'la Dark Fate) and doing a utube video stating how he thinks its an awesome idea to continue the legacy of Titanic for the current generation blah blah bs. but whichever studio owns the rights (Fox/Disney or Paramount) probably dont even need Camerons permission or blessing lol
could break 2b if done right
