Hello everyone! to those who are a fan of Korean movie..which movie stars Song Kang ho should I watch first? (yup,I haven't seen any movie of him yet and I want to get into Korean movie..I usually watch Japanese movies)

I haven't watched enough of his movies to make a really informed recommendation, but maybe try some of his older stuff like JSA, Memories of Murder, or The Quiet Family, and then work from there? As for his newer works, there's a ton, but I loved The Throne and, of course, Parasite. Seriously, the guy's mesmerizing in whatever role he played, so I think you couldn't get wrong choosing any of his movies.

I agree with kura2ninja.  I would add A Taxi Driver to that list. I really enjoyed this movie ^^

I would also recommend A Taxi Driver. It is a great movie and the story is fantastic. I think it is the ideal movie to start with.

After that you should definitely watch

The throne

Parasite (it is on cinemas now)

Memories of murder 

The attorney 

Thirst (this is not for everyone, but it is a great movie in my opinion)

Joint Security Area

I so agree, Definitely starts with A Taxi Driver

Then for his other movies, check out:

  • Synpathy of Mr vengeance
  • Joint security area
  • The Attorney
  • Parasite
  • Secret reunion
  • Snow piercer
  • The good the bad and the weird 
  • the face reader
  • Secret sunshine
  • The host
  • Memories of murder

Parasite   - awesome movie and he is awesome in it!

The top five I recommend is: 

1. The Host - this movie explains a lot of his acting style. Natural, comedic, and also intense. 

2. Memories of a Murder 

3. Sympathy for Mr. Vengeance 

4. Joint Security Area

5. Snowpiercer 

Definitely check out Sympathy for Mr. Vengeance.
