With an inquisitiveness recalling Richard Linklater and a feeling of tragic wonder, writer/director Graham Parkes’s feature directorial debut is an assured, complex story about two people with a love so strong it could literally move mountains.

Hawke and Pullman are both consistently spectacular, the kind of young stars who inspire hope for long careers every time they’re on screen.

It’s a goofy premise that would be done no favors by thinking about the rules too hard. So, wisely, Parkes does not really try. Instead, he applies it as a Charlie Kaufman-lite thought experiment focused on exactly two people.

This sci-fi romantic comedy introduces us to a premise as delightfully original as it is profoundly human.
