This consists of interviews with the crew, all of whom have something compelling to add within their area of expertise(and there is a very clear love of what they're working on), as well as clips from the subject.. It goes into, you guessed it, easter eggs.
It's 5 minutes long. This is found on the DVD of Spider-Man: Into the Spider-Verse. It spoils a lot of the title, but this review doesn't.
They talk about why they add them. Highlight a bunch of the different ones, urging us to find the rest. Some of them are deep cuts, others are more or less random. They put some of the filmmakers in there.
I recommend this to any fan of the property. 8/10.
