By Society & Culture & Entertainment Last updated Tuesday, April/09/2024

Here is a list of the main cast and characters on the CBS series Harper's Island.

Elaine Cassidy as Abby Mills, "The Good Girl"

Abby Mills is a natural beauty in her mid-20s who hails from Harper's Island. She is the groom's best friend and his wedding brings her back to the island for the first time since her mother was murdered seven years ago. Abby's father, the local sheriff, gunned down the psychopath at the end of his killing spree, but the event shattered Abby's relationship with her dad and left her haunted by her mother's death and the memory of the man who killed her.

Christopher Gorham as Henry Dunn, "The Groom"

Henry Dunn is a pauper marrying a princess. While growing up, Henry worked summers on Harper's Island, tending to the boat of real estate mogul Thomas Wellington. Now he returns to the island as the fiance to the mogul's beautiful daughter, Trish Wellington. Henry may have won the heart of Trish, but he still faces stern resistance from his soon-to-be father-in-law who disapproves of Henry and would love nothing more than to see this wedding never happen.

Katie Cassidy as Trish Wellington, "The Bride"

Trish Wellington is the radiant bride-to-be who loves Henry Dunn with all of her heart and can't wait to marry him. Money is no object for a Wellington, so Trish's perfect wedding comes in the form of a grand week-long stay on Harper's Island, full of activities, food and fun for her family and closest friends. Trish doesn't care about Henry's lack of pedigree, but she is "Daddy's Little Girl" and finds herself torn between the two men in her life.

C.J. Thomason as Jimmy Mance, "The Old Flame"

Jimmy Mance is a local fisherman who couldn't be happier about the Wellington-Dunn wedding coming to Harper's Island because it brings Abby, his high school sweetheart, back to the island. Jimmy immediately renews his pursuit of Abby, even though he harbors some resentment toward her; in seven years she never wrote or called. The years have been difficult for Jimmy, and he did some things that Abby will find very surprising.

Gina Holden as Shea Allen, "The Maid of Honor"

Shea Allen is Trish's big sister and the Matron of Honor. From the outside, she appears to have it all a great husband, a beautiful daughter and all the money in the world. But nothing is as it seems. There are problems in her marriage and her daughter Madison is acting out. The stress of keeping up appearances has Shea trapped in a life she never wanted for herself.

Richard Burgi as Thomas Wellington, "The Father of the Bride"

Thomas Wellington is the father-of-the bride. He's a conservative real estate mogul. He only wants the best for his daughter; but as far as he's concerned that doesn't involve marrying Henry Dunn. Mr. Wellington is accustomed to getting his way, and plans on stopping this wedding at all costs.

Claudette Mink as Katherine Wellington, "The Stepmother"

Katherine Wellington is the very definition of a trophy wife; a sexy woman closer in age to her stepdaughters than her husband. Trish resents her, but Shea tolerates her because she makes their dad happy. But considering Katherine's secret dark desires, that might not be for long.

Harry Hamlin as Uncle Marty Dunn, "The Uncle"

Uncle Marty is a surrogate father to Henry, the only family besides J.D. he has at the wedding. Uncle Marty loves being the center of attention; he started partying sometime in the '70s and just never stopped. But behind his blithe demeanor is someone who cares deeply for Henry, who would do anything to protect him. And behind that is a guy who pops pills when no one is looking while toting around a bag stuffed with bundles of cash and a gun.

Jim Beaver as Sheriff Charlie Mills, "The Sheriff"

Sheriff Mills is the law on Harper's Island, the man who killed John Wakefield, and Abby's father. He ended Wakefield's deadly rampage seven years ago, but not before Wakefield took the life of his wife, Sarah. In his grief, Mills sent Abby away, and now that she's back for the wedding, he hopes to reconcile with her. But times have changed, and Sheriff Mills has some dark secrets he has no intention of sharing with his daughter.

Victor Webster as Hunter Jennings, "The Other Man"

Hunter Jennings was Trish's college boyfriend. He's from a family as affluent as the Wellingtons. He's exciting and passionate and every bit her equal. He's also selfish and completely unreliable, which is why Trish broke up with him. But now that she's getting married, Hunter has shown up uninvited, hoping to convince Trish that he's the one she should be marrying.
