Marvel Studios' Avengers: Infinity War - Official Trailer

This has to be the last Avengers: Infinity War trailer, right? I feel like there've been a hundred of these things at least. The Thor: Ragnarok blu-ray had a boatload of behind the scenes stuff too. It's like I've seen half the movie already.

Anyhoo, it looks really good. I saw some site already talking about how before watching it you HAVE to watch Guardians of the Galaxy again. I guess they're right in a way. I mean I'm crazy well versed in comic book nonsense so I think I take for granted the fact that there are some details about Thanos in the movie that are kind of important to know. The kinds of details that are easy to forget in a 2 hour movie where the Racoon and the Tree steal the show.

I'd recommend going back and watching all the Marvel movies that feature the Infinity Gems Stones. So we're talking: Captain America: The First Avenger
Thor
The Avengers
Thor: The Dark World
Captain America: The Winter Soldier
Guardians of the Galaxy
Avengers: Age of Ultron
Captain America: Civil War
Doctor Strange
Thor: Ragnarok

Although looking at that list you could probably easily remove Thor, Winter Soldier and Civil War. The Stones aren't a big part of those movies, if pressed for time you could lift Captain America: First Avenger out of there too. The Tesseract (which hold a stone) is also heavily featured in The Avengers so you don't really need to double dip. Here's what I'd watch for sure:

The Avengers
Thor: The Dark World
Guardians of the Galaxy
Avengers: Age of Ultron
Captain America: Civil War
Doctor Strange
Thor: Ragnarok

If you watch all those, you'll know where each stone is currently in the MCU. Honestly, it's probably not THAT important to enjoying Infinity War that you even know that, they'll probably recap all of it at the start of the movie but hey, you could do worse with 14 hours of your life.
