The Aeronauts ★★★½

Wouldn't have thought a story about two scientists going up in a balloon, far up above the clouds would be as heart racing, and it is when they go too high and start to face the thinning air and frigid temperature. The film cleverly bows out at slower moments into flashback mode to deepen the characterization.

A solid Amazon Original film. It opened in some theaters. Would have looked good I bet in IMAX as it was shot in IMAX. Recommended.
