1. Robert Downey Jr. was in the MCU as Tony Stark, in fact, the original contract only signed the "Iron Man" trilogy, and his appearance in the three "Avengers" is a single contract. And Iron Man in "Captain America 3: Civil War" and "Spider-Man: Homecoming" is signing a new contract for each movie. During filming, Downey also asked to move the furniture of his Home in Los Angeles to the set of Atlanta in "Avengers 3", and the filmmakers agreed to this request. This is something that only Downey can do, other actors don't learn, just look at it.
2. In Avengers 3, Bruce Banner communicates directly with the Hulk, which is really the first time in the MCU. There was also a first , " Vision " Paul Bethany " , although he had already dubbed "Jarvis", but this was the first time he had revealed his true face in the MCU.
3. The release date of Avengers 3 was announced at the time of production of Avengers 2, and it was the first Hollywood non-documentary film ever shot entirely from start to finish with an IMAX camera, although it did not use the traditional 1.43:1 IMAX ratio, but 1.9:1. The "Airport Battle" scene in "Us Team 3" was the first clip in the MCU to be shot with an IMAX camera, and "Reunion 4" was also shot with an IMAX camera.
4. Downey, as Sherlock Holmes in Sherlock Holmes, has previously worked with both "Watsons"—the (fake) "Mandarin" Ben Kingsley (1988 Sherlock Holmes) and the "Hipster" Martin Freiman. This time, he finally worked with Benedict Cumberbatch of the British drama "Sherlock", and only Ian McLean, who also played Sherlock Holmes, was eliminated by three people.
5. The "Wakanda" place name first appeared on the screen of S.H.I.E.L.D. in Iron Man 2. The place is located on the border between Kenya and Ethiopia, next to Lake Turkana. In real life, this area is known for its abundant mineral reserves – a property of Wakanda. The "vibranchkin" in the film is compared by director Ryan Coegler to Coltan, which is closer to the real-life Congolese coltan. The word "Wakanda" comes from the Kenyan tribe of "Wakamba", also known as "Kamba".
6. "Nagiya" Lupita Nyonio and "Mbaku" Winston Duke were actually classmates at Yale Drama School, and the two watched "Reunion" together in 2012, and said that they hoped to one day star in a similar movie. So people still have to have dreams, in case they come true.
7. The character of "Black Panther" was created in July 1966, just two months before the creation of the famous "Black Panther Party". Many people think that "Black Panther" comes from the "Black Panther Party" (in fact, it does not), so at one point "black panther" was changed to "black leopard" (Chinese "black leopard"). However, because the response was not enthusiastic and no one cared, it was quickly changed back.
8. "Black Panther" is the first north American box office in the MCU to exceed the production cost in the first weekend, the budget of this film is about 200 million US dollars, and the box office on Thursday, Friday, Saturday and Sunday in the first weekend adds up to 202 million, which is too scary. This character is also Marvel's first comic book character whose film rights have been sold and can be recovered — the previous copyright holders were Artisan Entertainment and Columbia, which were returned to Marvel in 2005.
