Avengers: Infinity War is a tough act to follow. Not only is it one of the most successful blockbusters of all time, it also ended on a cliffhanger that left no room for copping out. Thanos eradicating half the universe in the film act isn't the kind of thing that can be reversed without shedding blood, sweat and tears along the way.
With this in mind, Avengers 4 has an unenviable task on its hands. The Russo Brothers' follow-up has to revisit that cliffhanger and resolve it in a satisfactory way, while also bringing the curtain down on everything that came before it.
If interviews from the directorial duo, the movie's writers and its cast are anything to go by, Avengers 4 will be just as unpredictable as Infinity War and include twists just as memorable as Thanos's 'snap'. These are bold claims, but Marvel Studios' recent track record suggests it is capable of delivering on them.
Avengers 4 is still shrouded in secrecy, to the extent that its title is yet to be revealed. What little the fans know comes from set leaks and rumours, but luckily, that's more than enough to make a few predictions about the biggest twists that lie in store.
