Thank you R179. Out of the current cast, "Friends Of Frank" are
Michael Easton (Frank has been a fan of his since his days as Tanner on Days Of Our Lives & Caleb/ on Port Charles. When Roger Howarth left OLTL for ATWT in 2003 (which coincided with PC's cancellation later that year) Michael was offered his choice of portraying either recast Todd or a newly created role, which was how John McCain came to be.
Roger Howarth (Close since their OLTL days, there was a slight dustup when Roger quit to join ATWT in 2003. They made up when Roger returned to OLTL almost a year after ATWT's cancellation; Frank was having creative issues with Trevor St. John around that time (Trevor was closer to Ron C.) so ABC wanting Roger back became something Frank wanted too (they even moved up Roger's return, due to OLTL's impending cancellation)
Kirsten Storms (Frank's "niece" quickly became close with him once she returned from her nearly year long medical leave of absence, devastating Jen Lilley, who grew comfortable in the role, even though she was hired as a temp. Frank constantly tries to push romance upon romance on Maxie to revive her popularity while also propping whatever new male he wants to push at the moment).
Kelly Monaco (Frank admired her from Port Charles as well and her friendship with Michael Easton, combined with her icy relationship with Steve Burton, who pissed Frank off when he jumped ship to Y&R to work with Jill in 2012, pushed them even closer. Kelly's issues are usually with her storylines not her buddy Frank)
Laura Wright (Frank became close with her after he saved her from being fired shortly before his arrival. After Jill (whom Laura is a friend of) was let go, there was nothing stopping then headwriter Garin Wolf of writing her out in favor of Tamara Braun returning as Carly (if not Carly, Garin was willing to have Tamara as a recast Kate). Frons didn't seem to mind, since he was on his way out anyway. Frons hired Frank in Jill's place which prevented Garin's plans (Kelly Sullivan was hired as Kate; Frank and Tamara weren't close back then) and Ron was also hired in Garin/Shelley Altman's place which changed Carly- Garin was planning on keeping her as a schemer while Frank/Ron sort of softened her like they did Blair (LW is also a known ass-kisser, always one of GH's number one cheerleaders which Frank appreciates.)
Finola Hughes, Genie Francis (Frank is fans of theirs & their characters; at one point, there were some slight instances where Frank and Finola had disagreements over him doing last minute rewrites and storyline changes; Finola was also "allegedly" sent home by Frank one day, and she has even threatened to quit, although Frank ironed it out and asked her to stay.) Genie's issues were working with Tony G. (another friend of Frank's during his time there) which is why she became a permanent fixture after Tony's retirement.
All of the new hires post 2012 were favored by Frank since he hired them, and he's a big fan of Y&R so he never hesitated to keep drawing from that well. Some he got rid of (Teresa Castillo, ex-Sabrina, however that was a budgetary issue since what would have been another four-year contract renewal for her went to Chloe Lanier's Janelle instead) mainly because he's strict with the finances and always keeps GH under budget (which is one reason why ABC has kept him all these years; Jill is known for notoriously going over the budget).
