From ‘Crash Landing on You’ to ‘Queen of Tears’, these K-dramas serve up all-star ensembles, legacy reunions, and surprise appearances that stole the show
Whether you’re in it for the cameos, the chemistry or the on-screen reunions that feel like fan service from the casting gods, these star-studded K-dramas make sure no scene goes unnoticed.
There are dramas—and then there are events. These are the kinds of productions where you’re not just watching for the plot, but for the possibility of another A-lister turning up. A legendary script? Always a plus. A swoony romance? Of course. But nothing sets off fan frenzy quite like a cast so stacked it feels like an awards-show seating chart. From blink-and-you’ll-miss-it cameos to dream ensemble pairings, these K-dramas understood the assignment: maximum plot, maximum star power.

2. ‘Crash Landing on You’ (2019-2020)
Starring: Son Ye-jin, Hyun Bin, Kim Jung-hyun, Seo Ji-hye
Cameos: Kim Soo-hyun (in full Secretly, Greatly regalia), Choi Ji-woo (as herself)
Part forbidden romance, part political fairy tale, this drama didn't just unite North and South Korea (fictionally, of course) — it also united some of Korea’s most bankable stars. Son Ye-jin brings grace and grit as chaebol heiress Yoon Se-ri, while Hyun Bin melts screens as stoic North Korean officer Ri Jeong-hyeok. The supporting cast? Already leads in their own right. And just when viewers thought the casting couldn't get better, in walks Kim Soo-hyun as his undercover agent character from another film universe, and Choi Ji-woo as a wink to her legacy in K-drama royalty. It’s less of a drama, more of a constellation.
3. ‘Queen of Tears’ (2024)
Starring: Kim Soo-hyun, Kim Ji-won, Park Sung-hoon, Kwak Dong-yeon
Cameo: Song Joong-ki
Hae-in (Kim Ji-won), a chaebol heiress, and Hyun-woo (Kim Soo-hyun), her husband from humble beginnings, find their love tested when she is diagnosed with a terminal illness. Melodrama, power struggles, and emotional gut punches ensue—but it’s the prestige cast that elevates this makjang-meets-romance to K-drama elite. Song Joong-ki’s surprise cameo as Vincenzo Cassano made fans collectively lose their minds.

4. ‘Squid Game’ (2021-ongoing)
Starring: Lee Jung-jae, Lee Byung-hun, Park Hae-soo, Wi Ha-joon, Jung Ho-yeon, Heo Sung-tae
Cameos: Gong Yoo
This isn't like the other K-dramas on this list. Here, hundreds of desperate contestants compete in deadly children's games for a cash prize. What could’ve been schlock turned into global television thanks to sharp writing and a cast filled with award winners and rising stars. Gong Yoo appears just long enough to slap someone and leave us wanting more, while Lee Byung-hun adds gravitas in his late-season role. Season 2 upped the ante with Park Sung-hoon, T.O.P., and Im Si-wan joining the mix.
5. ‘Goblin (Guardian: The Lonely and Great God)’ (2016-2017)
Starring: Gong Yoo, Kim Go-eun, Lee Dong-wook, Yoo In-na, Yook Sung-jae
Cameos: Kim So-hyun, Jung Hae-in
A 939-year-old goblin (Gong Yoo) searches for his bride to end his immortal life—only to fall in love. Add a dashing Grim Reaper (Lee Dong-wook) and you’ve got Korea’s most poetic supernatural roommate comedy. The ensemble chemistry is legendary, but even the cameos (like Jung Hae-in as Kim Go-eun’s first crush) hit hard.

6. ‘Descendants of the Sun’ (2016)

Cameo: Lee Kwang-soo
Captain Yoo Shi-jin (Song Joong-ki) and Dr. Kang Mo-yeon (Song Hye-kyo) fall in love amidst war zones and natural disasters. It’s romantic, glossy, and unashamedly cinematic. The supporting actors became stars in their own right, while Lee Kwang-soo’s brief but hilarious role proved even military dramas need comic relief. World-famous K-pop girl group Red Velvet even makes an appearance!
7. ‘Mr Sunshine’ (2018)
Starring: Lee Byung-hun, Kim Tae-ri, Yoo Yeon-seok, Byun Yo-han, Kim Min-jung
In early 1900s Korea, Eugene Choi (Lee Byung-hun), an American soldier born into slavery, returns to Joseon and finds love and resistance. It’s an epic tale of patriotism and doomed romance—written by Kim Eun-sook, directed like a movie, and acted with theatrical precision by an A-list cast whose chemistry burns hotter than the set lighting.

10. ‘Hwarang: The Poet Warrior Youth’ (2016-2017)
Starring: Park Seo-joon, Go Ara, Park Hyung-sik, Choi Min-ho, Kim Taehyung (V)
A drama about a secret group of elite warriors in the Silla Kingdom…played by some of K-pop’s most handsome exports. This show is chaos, eyeliner, and bromance, but the cast is a glittering list of stars. Watching it today feels like opening a very expensive yearbook.
