They’re both really entertaining, fast paced movies

Kang Dong Gu is an elite grave robber. He works with ancient tomb mural expert Dr. Jones and legendary shoveler Sabdari. Meanwhile, curator Yun is an expert in ancient art. She offers an attractive but dangerous deal to Kang Dong Gu.

both movies center on a heist that seems impossible to pull off.

both feature a team of experts recruited for the heist

they have the same vibes (in that the grand heist is a historical movie and collectors revolves around ancient artifacts)

both are entertaining and heartfelt at the same time

While Collectors is a movie that centers around a heist (rather than swindling per se) it is similar to The Swindlers in the sense that it is about a group of criminals who strive for a common goal: to get rich (and take revenge). This is your typical action-packed (yet fun) watch.
