What is your linear timeline theory?
Why yes there is!
http://www.animecrazy.net/search/Naruto-movies
They aren't shown in order, so I'll show you:
Naruto the Movie: Ninja Clash in the Land of Snow
Naruto the Movie 2: Legend of the Stone of Gelel
Naruto the Movie 3: Guardians of the Crescent Moon Kingdom
Naruto: Shippūden the Movie
Naruto Shippūden 2: Bonds
Naruto Shippūden 3: Inheritors of the Will of Fire
I personally like Inheritors of the Will of Fire the best, next Ninja Clash in the Land of Snow, and third Naruto Shippuden the Movie.
And then there are also three OVA's that sorta act as mini-episodes/movies that are also non-canon to the series (but entertaining to watch).
Naruto Special: Battle at Hidden Falls. I am the Hero!
Naruto Special: Find the Crimson Four-leaf Clover!
Naruto: Konoha Sports Festival
I don't really believe any of those three go in any specific order (they all have young Naruto and Sasuke is still with Konoha).
