this dvd should stickers on the cover saying "from the people who made Robert Downey Jr 3" & "its based in same world as Robert Downey Jr" & "featuring stuff that will used as extra's in Robert Downey Jr and the others 2" & "special feature "Hail to King" where we confirm we are making awful comedy's because we think our audience is stupid also and we need to milk out much out the sole popularity of Robert Downey Jr"
then at the bottom in tiny text possible "contains thor 2 dvd"
Marvel came very close to reboot with Age of Ultron, It was supposed to be 2012 event with a different ending, which would lead into marvel now! but marvel panicked and abandoned the idea.
Marvel is also willing to allow dumb idea to float around in continuity unlike DC, so for yes once magneto was turned into a baby, and yes once there was a clone saga or hulked out heroes or a superior spiderman, these are all still part of Marvel's history.
DC on the other hand clearly prefers to wipe these things from existence, so no one will remember batman's camp days, or that time the justice league got turned in apes or teen titians got turned into adults while the justice league became teenagers (OH YES THESE HAPPENED In the late 90's early 2000)
I think also marvel is bit more flexible with its character, it always finds silly way to mess up their characters and then after 2 years resolve it as if it never happened. DC on the other hand struggles with this. Grant Millar's batman run maybe the closest thing to what marvel do with everyone of their characters
