And past that I can't remember exactly what others I've seen that trope in.
I guess the Avengers counts...though it doesn't look QUITE the same and is a much bigger part of the plot..
Yeah, I definitely think The Avengers is responsible for set off the rash of recent skyportals appearing in tentpole films.
You're right, the plot device of trying to stop the aliens getting through has been borrowed along with the look.
I didn't even think about Iron Man, but that wasn't really a portal, just a blast of energy -- I can totally let that slide. Although, the look of the blue energy has definitely been borrowed (but The Avengers portal was also blue wasn't it?).
That finale was probably one of the best ones Marvel has done along with Civil War.
