Geek-Out: Essential Films to see before Avengers Infinity War
With the release of Avengers Infinity War, Marvel has almost completed Phase 3 of the Marvel Cinematic Universe (MCU). This is the 19th film in this series and though they're all connected, you don't need to have seen them all in order to understand what is going on in Infinity War. These are the ones we recommend you watch before going to see the big crossover that draws in almost all the major players in the MCU. 
All seven of these films are available at our Library, except for Black Panther which hasn't been released on DVD yet. You can find them in our catalog here.
