8 Amazing Movies That Only Feature One Actor

8. Buried

If the words "Ryan Reynolds trapped inside a wooden box for 90 minutes" don't do anything for you, don't worry, that's a justifiable response, especially since he's not playing Deadpool in the aforementioned scenario.

Buried is not the ideal movie for claustrophobics. It's not a great date movie for anyone with severe taphophobia. It is, however, a surprisingly tense thrill ride considering the entire thing takes place within a human-sized box.

In the opening seconds of the film, you're immediately placed into Reynolds' headspace. Which is basically "Oh f**k, why is it so dark and difficult to breathe?" followed by "Oh thank goodness I found a light so I can see exactly how f**ked I am inside this tiny, wooden casket."

Reynolds plays Paul Conroy, an American civilian contractor is buried alive in Iraq after his convoy is attacked by Iraqi insurgents. That means Buried has to find a way to ratchet up the tension without ever changing the physical environment, relying solely on Reynolds' facial expressions and brief interactions with the outside world via cell phone.

Unlike other protagonists in these types of movies, Reynolds' portrayal feels more approachable because he doesn't have a super secret weapon to use from his backstory. He's not a specialist in getting out of these situations and reacts pretty much how any normal person would when tasked with being buried alive. Which makes it all the more terrifying to sit through.
