What is the reason for the official runtimes of certain movies, such as Apartment (1996), being longer than their downloadable versions?

I mentioned "legal" because many unofficial versions are circulating online nowadays, and I want to understand the difference without those fake and illegal versions affect.

Legal means nothing without context. Are you talking about finding it on a like Netflix or other recognized streaming service? Are you talking about non-bootleg DVD or BluRay discs (not bought from some schmuck on a corner) but in a big box store?

1. I never seen the film.

2. It doesn't have THAT many votes. It has 16k votes.

3. It looks like it only had a DVD premier in the US back in 2006.

You haven't given ANY CONTEXT as asked for. Could you be talking about its latest July 28, 2021(DVD premiere) in Egypt? You do realize that movies get censored in different ways depending on the version sold in their respective market. I wouldn't be surprised that Egypt got a censored and shortened version.

That movie was just an example of the main question!

I won't talk about that specific movie, so could you please give me some information on the main question?

I'm not a mind reader. I don't believe they exist. Strange you think otherwise.

Did you read my answer? i suspect you actually didn't. 

Maybe next time? Offer CONTEXT as requested.

Movies get censored/edited in different ways depending on the version sold in their respective market. TV cuts exist. To make it broadcastable - remove sex or certain acts of violence and gore.

Hello sorengenus250cc, 

This is all covered in our Running Times help article. Only one running time is shown on a title's main IMDb page. This should be the running time of the title's original release in its country of origin. To identify this running time, we will use any item with a blank attribute, and a country field that is blank or matches the title's country of origin.

Thanks a lot
