Interstellar is many things. It is a descendant of 2001: A Space Odyssey (1968) and the direct descendant of Contact (1997), midwifed by Avatar (2009) and Gravity (2013). It is the most ambitious film of Christopher Nolan’s career, incorporating theories of wormholes, time and gravity into a story of space travel in the midst of environmental devastation that, perhaps appropriately for a film with apparent familial connections, explores themes of family, hope and love. It is a near-three hour spectacle of epic proportions that delivers awe-inspiring visuals as well as exquisite detail in the production design. It utilises Nolan’s trademark crosscutting techniques to tie together sequences for greater impact. It centres on a father-daughter relationship, beautifully played by Matthew McConaughey and Mackenzie Foy (later Jessica Chastain) along with a cast that includes Nolan alumni Michael Caine (obviously) and Anne Hathaway, along with Topher Grace, Casey Affleck, Matt Damon, Wes Bentley and Ellen Burstyn. It is a eulogy for NASA and a lament for the abandonment of space travel and all that represents for human endeavour and ingenuity. And it is an attempt to blend hard science (both fact and fiction) with an emotional story of broken families.
At times, Interstellar achieves the heights of its ambition, utilising its extraordinary scale to move its audience both emotionally and intellectually. At other times, the balance between science and sentimentality is lost and some scenes feel awkward. Explaining love as a dimension within the universe is ultimately unconvincing because love is at its most dramatic when it is not quantified. Love is the ultimate mystery that is most dramatic when left unexplained, and Interstellar’s attempts to incorporate love into scientific calculations do not work.
Perhaps ironically, Interstellar’s greatest weakness may be its insistence upon science, in the sense that everything is observable and quantifiable. A great strength of Nolan’s previous work is ambiguity. How much of Memento can be trusted? Who did what in The Prestige? Was everything justifiable in The Dark Knight? How much of Inception was a dream? Ambiguity is also used to great effect in Contact and 2001: A Space Odyssey – in neither film is it entirely clear what happened. Mysteries abound in Interstellar, but they are ultimately explained and, while the explanations are consistent within the logic of the film, they are also very pat: Eureka moments with the mathematical formula laid out in painstaking detail, which reduces the dramatic impact of key moments.
That said, while Interstellar overplays its (pseudo)science, it succeeds both as a visual and an emotional spectacle. The vastness of space is beautiful and awe-inspiring, as are the landscapes of Earth and other planets. The eponymous interstellar travel is breathtaking and humbling, while Nolan provides a number of action set pieces that rival the tension of zero-gravity combat of Inception and the impact of the street battle in The Dark Knight. Furthermore, the sentimentality of the father-daughter relationship is played with Spielbergian conviction, as recorded messages express loss and longing across separations of both long years and immense distances. The climax is an extraordinary special effects sequence of dazzling technical virtuosity, yet this sequence is sustained by a moving and affecting display of love. Interstellar may fail to explain love, but it does succeed at portraying love.
Ostensibly the film is about abandoning Earth and seeking a future on other planets. But as with any film, the events are open to interpretation. As with Nolan’s previous films, grieving and loss are major themes, and Interstellar suggests that part of loss is what we leave for our children, the importance of the future we create for them. Time is a variable within the calculations of Professor Brand (Caine) and the adult Murph (Chastain), but it is also a philosophical consideration for the film as a whole. What do we do with time? How can we maximise its utilisation and its availability for others? Do some people warrant more time than others and a species warrant more than individuals? Interstellar expresses a fundamental aspect of cinema: the capture and manipulation of time. Nolan’s work is often meta-cinematic, and just as a filmmaker rearranges time, temporal calculation and manipulation is intrinsic to the story, emphasising the importance of time and our use of it. Furthermore, the film undertakes that most fundamental task of cinema, especially science fiction – to transport its audience. Watching the film, I both felt myself transported beyond Earth and to a new perspective on time, all based upon concepts of love and hope. Interstellar is a flawed film, but it is an undeniably affecting and moving experience.
