Cinopsys
Interstellar is a rare combination: genuine physics, an enormous scale, and a story that is really about a father and a daughter. The films below each get at least two of those right.
Arrival is the closest match — hard science fiction built around a central emotional reveal, from a director working in the same register. If you want the pure spectacle instead, go to 2001: A Space Odyssey.

Frequently asked questions
What movie is most like Interstellar?
Arrival — the same blend of hard science fiction and a personal, emotional core. Ad Astra is the closest on the father-and-child theme.
Is Interstellar scientifically accurate?
Largely, by blockbuster standards. Physicist Kip Thorne advised on the film, and the black hole visualisation produced a genuine research paper — though the third act takes considerable licence.
What should I watch if I only liked the space parts?
Gravity and The Martian are the most purely survival-in-space of the list, with far less metaphysics.
