Spider-Man: Homecoming opens this weekend, and as usual with a Marvel movie there are a couple of scenes in the credits. If you want to be spoiled or not stay for them, this is what you’ll see after the movie.
The first credits scene happens right after the initial credits and likely sets up the villain in the sequel. Toomes is in prison and being escorted when he’s stopped by Mac Gargan. He even has a scorpion tattoo, setting up the villain he is. Mac asks Toomes if he knew who Spider-Man really was, and Toomes lies to him and says if he did he would’ve already killed him.
After the rest of the credits is a joke stinger of Captain America filming his PSAs. He make a comment about waiting for something you think would be important, only for it to be a waste of time, which is of course a joke about waiting for a scene at the very end of the credits.
Those are the only post-credits scenes in Spider-Man: Homecoming. As Venom is not part of the MCU, those “rumors” of that movie being set up in the credits are obviously bogus.
