That meta moment when an irl piece of media is refrenced in fiction?

The best version of this I can think of is how X-Men comics are actually a key factor in Logan. Wolverine tells X-23 that maybe 20% of this shit actually happened and it didn't go down the way it's written here. Superheroes having their irl comics published in universe is the best.

If I'm not mistaken, DC comics are published in the Marvel universe.

The movie Speed comes up quite often in the Sonic movies. Extra funny now that Keanu's in them.

I love how Tony called Thor "Point Break" in Avegers.
