As much as I miss all those in the cast who have died, I miss Michael the most. When I was living in New York, we frequented the same independent genre bookstore down on Chambers Street. His son went to Stuyvesant at the end of said street, so he tended to be there every week for B5 viewing parties with the owner and several of us fans. I asked him about the blue spacesuit he wore in "Babylon Squared" and he confirmed it was the unused blue suit from Discovery's pod bay in 2001. He had a serious nerdgasm when they pulled that out in wardrobe.
Then I moved to Japan and Sinclair was written off the show and I never found out why until years later.
Bruce and Claudia are wonderful to hang out with, too, though I have done that far, far too briefly. And Julie Caitlin Brown has organized several events a friend of mine has volunteered for. She knows I'm a B5 nerd so she sent me a pic of her with Julie while they were setting up. I responded with something along the lines of "I LOVE YOU, NA'TOTH!! ......... Or, I mean, tell her I said hi." Julie thought that was hilarious and we've been friends since. :$
All that and more is why I feel that cast and that crew in that place at that time are an unrepeatable phenomenon. I will hold out hope, though, that new leadership at WB in a few years might green light a new full-res transfer from the original 16:9 live-action film footage and do a straight VFX update in the same resolution, saturation, and aspect ratio.
