Get the Hell Out (2020)

Both are silly, light hearted, comedic zombie movies with a strong female lead and a little romance subplot. Both of the zombie apocolypsis are confined to a specific area mostly and one of the leads ends up providing the cure basically.

Both are comedic zombie movies that make use of specific stylistic choices. Theres also a central father-daughter relationship in both.

Both are thrilling action movies about zombies and a group of people trying to survive in a confined space (in train to busan its a train and in get the hell out its the parliament building). Some self sacrifices, some evil people who cause the deaths of others (but dont make it out alive) and a central father daughter relationship are to be found in both. Get the hell out is a lot more comedic though while train to busan leans into drama.
