Fans Marvel at epic Avengers climax

"We try to look at the characters behind the costumes. We try to think about them as very human people and we approach the storytelling in that way," says Anthony Russo.

"At the end of the day, what it's really about is very human, flawed people who are in difficult situations and trying to do their best. I think anybody can respond to a well-told narrative like that," adds Joe Russo.

While fans will be forced to bid farewell to some of their favorite superheroes on the silver screen (as Endgame trailers predict), some will find themselves rescuing the planet or restoring world order on smaller screens.

Disney is launching their new streaming service, Disney+, later this year. Five shows - an untitled Hawkeye series, WandaVision, Loki and Falcon and Winter Soldier - will be made exclusively available on the platform, with the respective actors reprising their formerly bigscreen roles. There will also be an animated series, titled Marvel's What If...?, which will feature the voice talents of some MCU stalwarts such as Hayley Atwell, who will reprise her role as agent Peggy Carter, according to reports by pop culture news sites Digital Spy and The Verge.
