Amy Berg's online series, with James Callis and Colin Ferguson
I just found out about this. Felicia Day is one of the producers.
www.imdb.com/title/tt3275400/episodes?season=1
I guess Episode 4 is James Callis's first episode. I watched that on youtube www.youtube.com/watch?v=uptzFXlfMUw (9 minutes, 29 seconds)
At the moment you can watch that episode and a couple of previous ones on Hulu by using the IMDb link, above.
Funny spoiler for James Callis's character:
Apparently his first line in the series is, "What year is this?"
I said, "It's 2010, Dr. Grant!"
(I know, it's Rockwell and 2014, now ;)
