What actors and actresses appeared in My Sassy Neighbour - 2005?

You're likely thinking of the 2005 South Korean drama "My Lovely Sam Soon" (also known as "My Sassy Girl" in some regions). It's important to differentiate this from the 2001 South Korean film "My Sassy Girl", which features a different cast.

* Kim Sun-a as Sam Soon

* Hyun Bin as Jin-heon

* Daniel Henney as Henry Kim

* Ye Ji-won as Yoo Hee-jin

* Jung Ryeo-won as Choi Hee-jin

If you meant the 2001 film, the main cast is:

* Jun Ji-hyun as the Sassy Girl

* Cha Tae-hyun as Gyeon-woo
