Beaten, kidnapped and tossed in a pit, Jin Soo Kwon hasn't had many pleasant days on ABC's hit drama "Lost."

He's stranded on a mysterious island with dozens of plane-crash survivors who don't speak his language and carry way more baggage than the suitcases they brought on ill-fated Oceanic Airlines Flight 815.

In real life, actor Daniel Dae Kim, 37, who plays Jin, the Korean tough guy, couldn't be happier.

He's enjoying living with his family on location in Hawai'i; he's earning a regular paycheck doing what he loves, and a day at the office means getting into filthy clothes and hitting the beach.

"I'm incredibly grateful for this opportunity," Kim said in an interview. "It's the most stability I've had in my career. I have a family, and to think about the fact that we're living in Hawai'i and I have a fantastic job, I can't think of anything better.

"Every day I'm at work and I look out at the ocean and see the crystal blue waves crashing on the beach, I just look up and thank the universe for putting me here."

Working on "Lost" (Wednesday, 8 p.m.) wasn't always so smooth for Kim, however.

In the series' Emmy-award winning first season, Jin was portrayed as a detached and chauvinistic thug who was overly protective of his wife, Sun. The character drew sharp criticism from some Asian viewers, who accused Kim of perpetuating stereotypes on national television.

"Initially, I was stung by it," he said. "I rejected a lot of roles that were one dimensional and put Asian-Americans in a bad light, so to receive the amount of criticism I did when the show came out, was hurtful."

But as audiences learned more of the character through flashbacks, and as Jin warmed up, so did his critics.

"All these characters have layers, secrets inside of them," he said. "It was difficult, but the thing that kept me hopeful was my trust in the producers."

Other characters started out in a positive light, but their dark pasts are being divulged this season.

"I really like Jin. I don't think he's the hard, stern character that he was initially laid out to be," Kim said. "I think he's very complex. I think he's very human."

Besides Koreans, "Lost" also features an Iraqi, blacks, a Hispanic, an Australian and a Brit among the large, diverse and mostly unknown cast compiled by creators Damon Lindelof and J.J. Abrams.

"In a way, this show has an opportunity to make a lot of commentary on politics, human relations, human rights," Kim said. "For Koreans, I think it's the best opportunity that American television has ever had to be visited by Korean characters once a week and learn what it is to be Korean."

Lindelof has said speaking English was not an option for Jin and Sun, who exclusively talk to each other in their native language (although Sun, it was revealed, speaks English). He noted that subtitles are not used when Jin speaks to other castaways, because he wants the viewer to share the frustration of trying to communicate.

The show is making a commentary on language because of "this sort of interesting American conceit, 'Everybody else on the planet should speak English,' " Lindelof said.

Kim, trained in classical theater, said acting in Korean has been a challenge and an opportunity.

Not only did he have to master the language quickly, but he tried to shed his rural Gyeongsang-do accent from the southeastern region of the peninsula, from which his family emigrated.

Jin did speak perfect English in a short scene in which Hurley, played by Jorge Garcia, was dreaming and speaking Korean.

"His pronunciation was fantastic," Kim said. "I was going around, saying maybe he should be the one speaking Korean and I'll speak English and say, 'Dude' a lot."

As Jin starts to communicate more with his fellow castaways, Kim is practicing broken English with a Korean accent.

Born in Busan, South Korea, Kim grew up in the blue-collar steel town of Easton, Pa. On a path to becoming a lawyer he decided instead on acting, an unpopular decision with his family.

After earning a master's from New York University, he had recurring roles on "24," "ER," and "Angel." He had small appearances in "Seinfeld," and "NYPD Blue," as well as on the big screen in "Spider-Man 2," "The Hulk" and "Crash."

"It's not about money or fame. I really enjoy the craft of acting," he said. "Whether it's on a small stage in front of 50 people or on a television screen in front of 20 million, it's still what I enjoy doing. It's the same."
