1. Would it make sense for Disney to release their movies earlier (a few weeks) on their streaming service than on Blu-ray and DVD?
2. How would you feel if Disney made a documentary about the production of certain films e.g. Marvel and Star Wars films?
3. Would it make sense for Disney to stream D23 exclusively on their platform?  

1. It would definitely make sense and be a good marketing tool for their service. As long as they still have the blu ray/dvd release it wouldn't have any downsides either.

2. I wouldn't give a crap. I don't like documentaries (unless they're about Polar Bears).

3. I had to google D23 to find out what it is. Some kind of fan club thing? I wouldn't feel any way about that since I simply don't care.

1. My first instinct was yes, but it really depends on if they make more profit from a bluray sale than a one month subscription (or the lowest price you can pay to subscribe.)  Whichever makes them more money should come first.

2. Don't care really, wouldn't watch it.

3. I've never even heard of it.

I'm still confused as to why they don't simply combine this idea for a Disney streaming service with Hulu. They will own 2/3rds of Hulu if the Fox deal is approved, and they could simply buy the other 3rd if they wanted to, they can afford it. Hulu already has an established subscriber base of 20m, with the power of exclusive Disney movies and shows, and an expansion into more countries, Hulu could become a powerhouse able to compete against Netflix.

It's going to be really hard for them to sell people on a separate $10 a month subscription just for Disney movies and Disney shows. 

Anyway, to answer the questions in the OP:

1. Would be smart for them to do that if they want to get alot of subscribers, though it might hurt blu-ray and digital sales. 

2. Wouldn't surprise me if they did. 

3. I could see them doing that.
