If you loved The Fourth Protocol, try Heart of Stone

A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.

What they share

Theysit in Action / Thriller territory. If that's the register that drew you to The Fourth Protocol, the second film will land in a comparable space — through a different lens.

What Heart of Stone is

A sleek high-tech lab at night, servers humming, screens glowing. A lone hacker infiltrates, a deadly weapon is at risk, an operative is closing in. This thriller lands best after a few big-budget spy films.
