I finally caught up on The Tick this morning and can confirm that was where you saw him. He plays Arthur's stepfather and his role gets bigger as the first season goes along (with a surprise at the end.)I actually saw him in two or three weeks ago in one of the CW's "arrowverse" shows... but it might also have been on the recent "The Tick" show.. it was a speaking role(10 words or so) the guy has to make a living, right?
"I would go to [the writers] and complain. But they would say, 'John, why don't you just say the words as written?' and I'd say, 'I'll tell you what, I will actually say the words as written when you can actually write intelligent sentences!'"
