10 Notable Movies Featuring (Mostly) Two Actors

6. Gravity

Alfonso Cuarón's sci-fi thriller is by far the most expensive movie on this list, boldly using a $130 million budget to craft a film featuring just two main actors.

Sandra Bullock and George Clooney star as two astronauts stranded in space following a calamitous accident, and they're the only two performers who are physically seen on screen.

We do occasionally hear some voices through their comms, including a Mission Control officer voiced by Ed Harris, but 99% of the film is just Bullock and Clooney (or as is eventually the case, just Bullock).

You can argue that this is conceptually less ambitious than many of the films on this list because the actors are able to use the visual effects as a crutch for their performances. Even so, in the hands of another director and other actors, Gravity wouldn't be anywhere near as effective.
