The Occupant

Javier Gutiérrez stars as Javier Muñoz, an unemployed executive obsessed with the new family that now lives in his apartment after he discovers the keys still fit. He becomes fixated on them and begins to infiltrate their lives, driven by denial and jealousy about his past wealth and happiness. The film is a gripping thriller exploring dark themes of identity theft and manipulation, though some plot points challenge believability. Javier's mysterious portrayal stands out, but supporting roles could use more depth.
