Captain America: Civil War - which opens in cinemas this week - will mark the 13th chapter in the ever expanding Marvel Cinematic Universe. These movies have been the standard bearers for superhero cinema - the kind of films that satiate the fanboys and fangirls while at the same time still possessing the kind of mass appeal that make them box office successes. It’s a winning formula and Marvel are currently the ones to beat. But what happens when you’re 13 movies in? What happens when you’re yet another superhero flick in a cinemascape that feels overrun with superhero movies?

This month, on When We Last Left Our Heroes, Umapagan Ampikaipakan speaks to Dr. Arnold T. Blumberg about Captain America: Civil War and whether or not we've reached peak superhero in cinema.
