Superheroes represent hope in a world full of conflict and it is up to the filmmakers to weave real-world issues in the storylines, says Avengers: Endgame co-director Joe Russo. Just like mythology, he says, superheroes appeal to a cross-section of people. So one can be a fan of Captain America for his morality while another would be attracted to Deadpool's amorality.

"They become important because they are archetypal, hopeful and accessible to the global audience. There is a lot of darkness in the world and we try to infuse thematics that are valuable on a global level to these movies. You can find the code, ethics or values you can identify with. It is no different to any mythology, Greek or any gods you can think of," Russo told PTI in a group interview.
