Similarity isolation and survival in a confined Space. The protagonist is isolated in his apartment during a zombie apocalypse, facing limited resources and threats. The isolation and survival struggle in a restricted environment parallel the scenario on the airport bridge.

While different in tone (one is more comedic, the other serious), both are about a group of people dealing with a zombie apocalypse.

They both take place in a very tall building during a zombie outbreak in Seoul. In this one the male leaded named Joon-woo wakes up to find out that a zombie outbreak happened after a late night of video gaming. He struggles to survive and is worried about his parents who left him home alone before all this chaos plays out.

Both are movies about people trapped inside a building during a zombie outbreak.

If Alive left you haunted by the loneliness of survival, Forgotten carries you one step further:
What if the people you survive for aren't who you thought they were?

Both explore isolation — but Forgotten twists it into something colder, stranger, and far harder to escape.

alive is about zombie and survival
the flu is about a disease
