Teaser reels for next December’s coming episode give no clues to the story, still less to how these old characters are returning via the multiverse

Avengers: Doomsday may still be almost a year off, but already it feels as if Hollywood has entered a new era of confidence marketing, built around a sort of ritualised roll-call of legacy characters who really need everyone to know they haven’t been retired yet. In the last few weeks we’ve had three almost completely pointless short trailers online, with another reportedly playing in cinemas ahead of Avatar: Fire and Ash. First there was Captain America cradling his baby, then Thor praying to his dear old dead omnipotent dad. This week we got our first proper look at the classic X-Men lineup in the new film, and there are suggestions that an encounter between the Fantastic Four’s The Thing and half of Wakanda is imminent.

Something weird is clearly happening. These aren’t teaser trailers in any meaningful sense, because these half-cocked, chord-drenched promotional entries tell us absolutely nothing about what is to come. Assembled fandom wants to know who Doctor Doom is in the new movie, and why he looks exactly like Robert Downey Jr’s Iron Man (because if this is just stunt-casting there are going to be walkouts). We want to know how all the Fantastic Four and X-Men have suddenly turned up in the main Marvel timeline, when the last 17 years of these movies made no mention of them whatsoever. And we’d really like it not to just be explained away by … “the multiverse”.
