Diane on GENERAL HOSPITAL — Everything You Need to Know


Diane Miller isn’t on GENERAL HOSPITAL that frequently, so it’s understandable if some fans may not be aware of her history in Port Charles. The character first appeared back in 2007 and has always been played by Emmy-winning actress Carolyn Hennesy. From criminal cases to custody battles and everything in between, Diane is the attorney you want on your side when you’re facing a judge!

Sonny Corinthos hired Diane to defend him in court and help him escape the long arm of the law. When he was accused of murdering Lorenzo Alcazar, the attorney advised the mobster to remarry Carly so she wouldn’t have to testify against him. She also defended Sonny’s top enforcer, Jason Morgan, who was also implicated in the murder, and got him cleared as well. Representing Kate Howard worked out nicely for Diane, as she loved fashion and Kate was the editor of a fashion magazine.

When Diane represented Elizabeth Webber in a custody battle against Lucky, she found herself pitted against his attorney, Alexis Davis. Working together to reach a settlement, the two lawyers became great friends. After drinking a bit too much, Diane went to Sonny’s house where she encountered an equally-drunk Max Giambetti, and the two had sex. Sonny was furious and threatened to fire Max over the relationship, but Max fought back and his boss backed off. Later, when Max showed Diane the engagement ring Sonny had bought Kate, she mistakenly thought he was proposing to her. They eventually cleared up the misunderstanding by admitting to each other that they weren’t ready for marriage.

After learning that Sonny, while engaged to Kate, had slept with ex-wife Carly, Diane asked Max if he’d ever cheated on her. His didn’t understand how he could have cheated since they were only in a casual relationship made her break up with him. He managed to woo her back but their relationship eventually fizzled out after a few years and they parted as friends.

Alexis began working with Diane as a partner to help defend Sonny against the charges that he’d murdered Claudia Zacchara. She also acted as Alexis’ attorney when she killed Kiefer Bauer in a hit-and-run. When Michael went to jail for Claudia’s murder, Diane helped get Jason convicted on the condition he would be sentenced to Pentonville with Michael so he could keep an eye on the young man. 

As a side project to her constant legal work, Diane teamed up with Damian Spinelli to help him write the adventures of his alter ego, Jackal, P.I.. When Jason caught wind, he warned them not to include him in any way or Diane would have to sue herself on his behalf.

More recently, Diane faced off against Nora Buchanan as she represented Lulu Spencer in her custody battle against Valentin Cassadine, and then defended Carly against charges that she had tried to kill Nelle Benson.

As long as there are people in Port Charles who need a good lawyer, Diane will be kept busy because she’s the best (along with Alexis). Stay tuned to see how her story continues, and for more GH news, keep reading the ABC edition of Soaps In Depth magazine.
