Deadly Devices
Nolan's Memento is a good example
of when messing with time works. The weird backwards/forwards/the-middle-is-the-end
order of events puts us into the protagonist's mind. Leonard Shelby has anterograde
amnesia, so he quickly forgets events, often within minutes, and has to rely on
notes, tattoos, and photographs to make sense of his disintegrating world. The
effect of Nolan's clever time-jumping device here is to make us, the audience, know
only what Shelby knows at each point in the story, so it enhances the
storytelling.
At first glance, Interstellar seems like another Nolan
time-warp film. It's a story about the relative speeds of time and the possibility
that the future could influence the past. But Nolan indulges his fascination with
time here without bending or rearranging the order of events. He sticks to
a conventional timeline to tell the story, and it works.
Two stories
where Nolan's time-warping devices don't work are Tenet and Dunkirk. Tenet, as that
particular saga's stats show, if you peep with a critical eye, was a boob. And while
Dunkirk was a success at the box office, it was a clunky experience to sit through.
With the land segment spanning one week, the sea segment covering one day, and the
air segment just one hour, it had a structure that repeatedly called attention to
itself.
This is Oppenheimer's problem. Just as in Dunkirk, in the story
of Robert J Oppenheimer, Nolan tries to tell too many stories, repeatedly jumping
between the 1940s Manhattan Project, Oppenheimer's 1920s student years, and the
black-and-white 1950s hearings.
The effect of jumping between times and
from colour to black-and-white to colour to black-and-white is to remind us, at
every transition, that we're watching a film.
And the second you remember
it's all just flickering images on a screen, a story's spell is broken.
