John Prosky
Prosky has landed roles in tons of hit shows. I guess it really started back on JAG when he played Jon Barrow. Of course, he later got to play David Finch on HBO’s True Blood. Anyway, if you like Medium, you know he played Tom Van Dyke. Oh Shonda Rhimes’ Scandal, he was Senator Gibson. We miss Scandal already!

Mark Costello
Mark Costello once was on our screens as Commander Onclay during JAG. Ever since that role, he’s been very active in the industry. To give you an idea, he’s acted in shows like, Chris Rock’s Everybody Hates Chris, General Hospital, Criminal Minds and The West Wing. Wow, that’s pretty impressive.
