There is no real rule of when one can add spoilers to a page. Since this is an international site, and if one wants to avoid spoilers, one has to proceed with caution on the pages they don't want to be spoiled on, and on the Wiki Activity page where certain spoilery categories are visible when added to pages.

The rule (or lack thereof) especially applies to movies and tv-shows, especially the former considering most Marvel-films are released worldwide before US-audiences gets to even watch them.

If you have new info to be added to a page that's very recent, don't be afraid to add them.
