I have never seen the Alvin and the Chipmunks films, but if you want to see them, then this is your day, because both Alvin and the Chipmunks films can be seen on Netflix.
The first Alvin and the Chimpunks film from 2007 can be seen on Netflix in Argentina, Italy, Portugal, Brazil, Spain, Mexico, Japan and Costa Rica and the second film named: Alvin and the Chipmunks: The Sequal can be seen in exactly the same regions.
If you live outside these regions but still want to watch Alvin and the Chipmunks on Netflix, then all you need to do is to follow the instructions in this article, and you will be able to start watching Alvin and the Chipmunks on Netflix right away.
And if you have seen them, why not write a comment and tell me whether or not I should watch the films as well, or if I should watch some other film instead maybe?!
