I looked up the cast list of the CW's Arrowverse's DC comics 5 partTV-mini-series Criscis on Infinite Earths baised "loosely" on the 12 part comic book series written back in 1985-1986, there is ONE name that to DC comic fans stands out over all the rest.
BURT WARD.
He was cast as Dick Greyson on Earth - 66.
Real comics geeks get it.
