400 Days

At the end of 400 Days, the story leaves viewers uncertain about what was real and what was simulation. The crew’s entire experience—marked by hallucinations, secrets, and mysterious occurrences—could have been either a realistic trial or a carefully constructed illusion. When they step outside into a seemingly post-apocalyptic world and meet Zell, it raises questions about whether the catastrophe aboveground truly happened, or if it was part of the simulation. The movie deliberately keeps these truths ambiguous, emphasizing that some mysteries in life are beyond understanding. This open-ended conclusion invites the audience to interpret whether their ordeal was a tragic real event or a complex psychological test.

As for the mission’s purpose, the film offers no definitive answer. Its stated goal sounds simple—exploring space and human resilience—but the crew’s flawed characters cast doubt on whether they were truly qualified or if the mission’s purpose was something hidden and more sinister. Characters like Theo, who shows irresponsibility, and others with secrets or mental strain, imply that the real reason for the mission might have been concealed from them all along. This adds to the overarching theme of distrust, where no one can be fully relied upon, not even among the crew or scientists overseeing them.

Director Matt Osterman has acknowledged that he prefers to leave the ending open to interpretation. He hints that the true emotional core is about the relationship between Theo and Emily, which he describes as a focal point of the story—highlighting that sometimes, what matters most in a confusing narrative is human connection rather than certainty. Ultimately, the ending challenges viewers to accept uncertainty and reflect on how humanity’s obsession with knowledge can sometimes lead to moral and ethical pitfalls. In the end, 400 Days reminds us that some questions about truth and trust may remain forever out of reach, and that’s perhaps the most profound message of all.
