7 Marvel Cinematic Universe movies aren't available to stream on Disney Plus. Here's why.

Why it's not on Disney Plus: Sony owns the film rights to "Spider-Man" movies and can keep them as long as it releases a movie every five years. The studio struck a deal with Marvel Studios in 2015 to allow the character to appear in the MCU. Sony would retain distribution rights to the character's solo movies while Disney would earn a percentage of box-office gross and all merchandising revenue. Sony and Disney struck a new deal this year for actor Tom Holland's Spider-Man to star in one more solo movie and appear in one other MCU movie. If Disney wants "Homecoming" on Disney Plus, it will have to strike another deal with Sony.

Why it's not on Disney Plus: "Ragnarok" is currently available to stream on Netflix. It's expected to leave Netflix next month, so it shouldn't be long before it's streaming on Disney Plus.

Why it's not on Disney Plus: "Black Panther" is currently on Netflix, but is expected to leave the service in March.

Why it's not on Disney Plus: "Infinity War" is currently on Netflix, but is expected to leave in June.

Why it's not on Disney Plus: "Ant-Man and the Wasp" is currently on Netflix, but is expected to leave in July.

Why it's not on Disney Plus: Like "Homecoming," Sony owns the distribution rights to "Far From Home" and the movie won't be on Disney Plus until Disney strikes a streaming deal with Sony.
