Marvel movies have been very successful overall since the release of Iron Man. From Iron Man to the Hulk, from the Avengers to the Guardians of the Galaxy, every superhero has impressed us.

These dozen Marvel superhero movies are strung together to form a vast Marvel Universe worldview. However, as the worldview grows larger, it is inevitable that there will be some loopholes (unsolved mysteries).
Today, Marvel will take stock of the 7 unsolved mysteries of Marvel movies. PS: Some of the movies mentioned below are not owned by Marvel, and if there are more unsolved mysteries, welcome to "write a message" at the bottom of the article to add!
1. Where did Mandarin go?
In the Marvel movie "Iron Man 3", there is a classic villain of Iron Man, "Mandarin". Originally thought that Mandarin would do some action (Mandarin in Marvel Comics is really too strong), but unfortunately in the end it was found that Mandarin is actually a comic actor.
This was already a slot in Iron Man 3, and perhaps to cover up that slot, Marvel later made a 13-minute Marvel short.
This short film reveals that the real Mandarin actually exists, although it does not show the real face, but it makes Marvel fans really excited. The name of the short film is "Long Live the King", interested friends can reply to the backstage of the public account "Marvel Fans" to enjoy this short film.
2, Black Widow revealed the secrets of S.H.I.E.L.D., and later?
In the Marvel movie Captain America 2, Black Widow and Captain America discover that Hydra has fully infiltrated the S.H.I.E.L.D. organization. So at the end of the film, Black Widow chooses to reveal all the secrets of S.H.I.E.L.D., including her own identity and experience.
However, subsequent Marvel movies do not mention this again. What do you think of S.H.I.E.L.D.? What do you think of the Avengers? Marvel movies seem to omit these links.
3. Who did Professor X kill?
In this year's movie "Wolverine 3", we know about the "Westchester Incident", but Wolverine Logan has been avoiding this incident.
No one knows the true source of the incident, no one knows who Professor X killed, and no one is sure why Professor X got out of control. Possibly, this will be an unsolved mystery for Wolverine 3.
4. Is the Red Skull dead or not?
At the end of the Marvel movie Captain America, the Red Skull and Captain America battle, and eventually the Red Skull is teleported to an unknown place by the Cosmic Cube. What about the life and death of the Red Skull? Also, whether the Red Skulls can reappear in future Marvel movies is unknown.
5) Where did the Hulk's girlfriend go?
In the 2008 film Invincible Hulk, we meet Betty, the Hulk's girlfriend. Betty is a very important character in the Marvel Comics, as she is one of the few characters who can calm down the Hulk.
Like the Hulk, her life was directly ignored by Marvel, and since "The Avengers", Marvel has not written any ink to describe the Hulk's ex-girlfriend, just like ignoring the Hulk and General Rose's feud.
6. How was the Rainbow Bridge repaired?
In the Thor film series, the Rainbow Bridge is an important means of transportation in Asgard, connecting the Nine Realms of Northern Europe. In the Marvel movie Thor 1, this beautiful rainbow bridge is destroyed by Thor.
However, in the Marvel movie "Thor 2", this beautiful rainbow bridge is actually repaired intact. As for who built it and how? There is no clear explanation at this time.
7. What happened to the murderer of Spider-Man's Uncle Ben?
In the Spider-Man film series, Uncle Ben is a very important character because he said to Spider-Man Peter Parker the classic saying that "the greater the ability, the greater the responsibility".
However, where did Uncle Ben's killer go? We have no way of knowing. We just know that Sha Ren explained the real story at that time, but what is the end of the real murderer, there is no explanation in the movie, maybe he is still wandering the streets?
The above are the 7 unsolved mysteries in the current Marvel movies (in fact, there must be more), welcome to "write a message" at the bottom of the article to add, see what other unsolved mysteries marvel movies have.
