Compared are the US Version (Netflix) and the Original Italian Theatrical Version (German DVD by Universum Film).

Besides a different intro, the Netflix Version lacks some humorous elements that make Guido look a little goofier. In addition to that, the entire subplot regarding Ferrucio's attempt to read his poems to the publisher.
Except for the end credits, the cut regarding Josue's birth is identical.

If not mentioned otherwise, the additional footage is only in the DVD Version. The time index refers to the DVD Version.
