Popular choice for the actor is Martin Sheen.
Another possibility from her IMDB: Edward James Olmos. Now here is the irony: they both lost their Oscar bids to Dustin Hoffman.
Anyway, lame blind item. I had never heard of the actress, or the porn guy.
Edit: Can't be Olmos, he won only one Emmy. I can't believe they dissed BSG -- award show still don't respect SciFi.
