Let's break this down: Michael Keaton starred as superhero Batman in Tim Burton's 1989 film. In 2014, he took the lead role in Alejandro G. Iñárritu's Birdman, a surreal metadrama about a washed-up actor who found fame playing a superhero.

This year, in Spider-Man: Homecoming, Keaton will play a supervillain who resembles 'Birdman' an awful lot. It looks like Keaton's come full-circle, deconstructing his most famous role and then, um, reconstructing it again.

That's probably appropriate for Spider-Man: Homecoming, which is the third 'incarnation' of the superhero since 2002. Perhaps there's no way to avoid the fact that this is well-trodden ground, and the film-makers have woven Keaton's reputation into the film's ironic knowningness. Or, probably, not. This is Hollywood after all.

The good news is that Tom Holland looks set to be the best Peter Parker yet, combining the wet-eyed winsomeness of Tobey Maguire (who played Spidey 2002-2007) with the cocky playfulness of Andrew Garfield (2012-2014). He also actually looks like the teenager who Spider-Man is meant to be, although this won't last. Marvel Studios is probably already eyeing up actors for a fourth Spider-Man, perhaps as yet unborn.
