I did finish 1984 on 31-Dec-83. Maybe I need to read it again, don't remember too many details...
For Fahrenheit 451 I have seen the movie twice and I remember it quite well. No idea how much it is different from the book, have not read it.
Of course not all aspects of those fiction works apply, especially outside of China, Russia and the like. But Orwell would be not have foreseen how Google/Apple/Facebook can use positioning info or face detection of their users or how Russian internet trolls can influence US presidential elections or German vaccination opponents.
I really don't mean to rail on you, but this confirms the parent comment's suspcisions quite precisely - having "seen the movie" about a book whose major point is the eradication of books in favor of more easily digestible media like movies; and having read the other book you mentioned almost 40 years ago, whose themes are completely irrelevant to Russian trolls or face detection...
You have read those books right?
