When I first watched TNG reruns (no DVDs) I thought Cmder Riker was the same character as Captain Thadiun Okona
because they kind of look similar. (As stupid as that sounds
Well Billy Campbell who played Okana was the first pick to play Riker before being dropped because they considered him to be too soft.
I hadn't heard that before. I knew Campbell had been in the running to play Riker, but I just assumed he had been passed over because Roddenberry, Justman and Berman preferred Frakes. I didn't know the reasoning behind it.
