I am probably not going to be home when they show the Astro Boy Reboot teaser, so I asked them about being able to watch it AFTER the official showing, and this is their answer:
The teaser will be broadcasted from 16:20 (french time) during our MAGIC event on march 21. You should be able to watch it on the Astroboy website from 16:30. And yes, you can watch it anytime after the release.
That means they will be keeping it up there where we signed up, so you don't have to stress about seeing it just that one time.
BTW I posted this question on their FB page (used Google translate to convert my question into French, but as you can see, they answered in English).
Interesting. They originally said 4:15 GMT+1 in the prior announcement
. I assume that's for "VIP access" as they call it, but it's funny, because you get to see it only a few minutes before it gets posted on the site.
I had no doubt that the teaser was going to be available to view afterward, considering streaming sites like YouTube. If Shibuya wasn't going to post it on YouTube, someone would've surely recorded it and put it on there later.
I might as well take this opportunity to remind everyone that wants to see the teaser live to find out the time that it airs in your time zone.

For my fellow North Americans, Eastern Time Zone will get VIP access at 11:15 AM and get to see the teaser on the official website starting from 11:30 AM. Pacific Time will get VIP access at 8:15 AM and will get to see the teaser on the official website from 8:30 AM.
