The Last: Naruto the Movie take place after the Manga chapter 700. And if I'm not wrong episode 441 is a filler and not part of main manga story that takes someplace after chapter 678 of manga. So you need to read the manga from 678 to 699 before watching The Last: Naruto the Movie, or you can wait for the anime to reach the point of chapter 699.
After that Naruto Manga chapter 700 take place, which act like epilogue.
Boruto: Naruto the Movie take place after Manga chapter 700 and Naruto Gaiden: The Seventh Hokage and the Scarlet Spring
, Gaiden is a mini manga series that takes place between chapter 700 and Boruto movie. Gaiden can be skipped but
You will miss how Sarada Uchiha accepted her family.
But I will definitely suggest to watch anime till it reaches chapter 699 before both the film, or read the rest of the story in the manga. Skipping gaiden is your choice, except about a character mentioned in spoiler.
