The Man From Nowhere involves the main character trying to save a young girl from Mafia type people. In Man on High Heels the main character is feared by all gangs and at some point must save someone he loves from one of these gangs. Similar violence and action.

Not really the same, but both had a similar vibe to me. Although Man on High Heels had a lot of violence and action, two weddings and a funeral was more of a drama and slice of life sort of movie. Both fall under the lgbt... genre.

Similar story about a woman who "sleeps" with someone much younger than themselves and then finds them dating that person while also being faced with a love triangle. They're a bit different but also very similar.
