NEW YORK •Should supporting actors be paid the same as leading actors in a television show?

While CBS did not address this issue, it did say on Wednesday that it had tried very hard to retain Daniel Dae Kim and Grace Park on crime procedural Hawaii Five-0 with "large and significant salary increases".

However, it could not come to terms with what the duo - who have been in all seven seasons of the show so far - wanted, entertainment portal Deadline reported.

Kim and Park sought the same deals enjoyed by co-stars Alex O'Loughlin and Scott Caan.

Some industry pundits had said that CBS did not want to set a precedent by paying everyone almost equally, even if their roles differed in importance.

In a note on his Facebook page on Wednesday, Kim, 48, noted: "As an Asian-American actor, I know first-hand how difficult it is to find opportunities at all, let alone play a well-developed, three-dimensional character like Chin Ho.

"I will miss him sincerely... though transitions can be difficult, I encourage us all to look beyond the disappointment of this moment to the bigger picture. The path to equality is rarely easy."

His decision to quit Hawaii Five-0 was also likely tied to the fact that his company has clinched a deal to produce The Good Doctor series, which will air on ABC this fall.
