Marvel movies love to make fans wait in the cinema until the very last credit has rolled.
Sometimes the eye-popping and teaser-packed pay-off can be more than worth it.
Other times fans realise they have been toyed with as a cheeky Captain America Public Service announcement rolls.
After the first official Thor-Ragnarok screening, Twitter already has sneaky leaks about the Thor: Ragnarok end-credits scenes.
ScreenRant is already reporting that Thor:Ragnarok only has two post-credits scenes.
Some fans have been hoping that Marvel would take the chance to show some of the Avengers Infinity War footage that was screened earlier this year as one of the after-movie scenes.
Most are still hoping that a proper full trailer will debut before every screening of the third Thor movie.
Some fans have already leaked on Twitter that one of the Thor:Ragnarok end scenes WILL include material leading into Avengers 3.
The fan tweeted: “According to sources, Thor Ragnaroks 1 of 2 Post Credit Scenes Will Lead into Avengers Infinity War.”
ScreenRant, so far, is refusing to spoil any surprises and only speculates what might be in the two scenes.
It seems likeley that one will, indeed, start to set up Infinity War, while the other will be a last chance for director Taika Waititi to have some fun with his characters.
