The Sci-Fi genre has always worked well in bringing thrilling, tension filled moments to the screen. While some have kept us on the edge of our seats due to a villainous alien threat lurking over our hero, the common trait for all the best heart stopping moments has been the strong characterisation of our protagonists.

Be it an anti-hero finally undertaking a positive action, a family battle coming to its epic conclusion or two astronauts working together to stay alive, the ability for the film to establish or develop character dynamics is crucial. Even when the common sci-fi trope of an alien threat is used to build up the suspense and keep us on the edge of our seats, it is our connection to the characters that is a key determinator for a scene's success.

There are several entries on this list that are from solid if not spectacular films, but are all worthy entries here due to perfectly nailing some key moments. The strong use of Mise En Scene combined with an eery sound score and backing track are present in each of these entries, while the acting is generally first-rate too.

So sit down and relax and try to ignore the strange noise from behind your couch, as we reflect on the 12 most heart-stopping moments in Sci-Fi history.
