"Battlestar Galactica" creator Ronald D. Moore paid tribute to Rhodes in a tweet after news of his death broke.
"Just heard that Donnelly Rhodes, Galactica's own Doc Cottle, has passed away," Moore wrote. "Very sad. He was a lovely man and I so enjoyed writing for him. Admired his work ever since 'Soap.' He will be missed."
A number of fans and followers responded to Moore's tweet.
"I just watched an old episode of Davinci's Inquest last night and there he was," one follower wrote. "Loved his performances where ever he was...such a broad spectrum. First saw him on Danger Bay as a kid. Loved that show. I thought he was the handsomest man ever."
"I first saw him on 'The Young and the Restless' [Young & The Restless] back in the 70's when he played Phillip Chancellor," another user added. "What a fine actor! So sad he has passed! Prayers for his family and friends."
"Just completed a re-watch of the series after 14 years," one fan responded. "Not only does it hold up, it’s better somehow. The casting (along with the writing of course) was inspired. He was wonderful in the role. So sad to hear of his passing."
