I’m behind on my Google Alerts (crazy couple of weeks), but I’m trying to catch up. Rabid Doll has this nice interview with FRINGE showrunner Jeff Pinkner that should shed more light on what FRINGE is “like” and “not like.” And he can say with more authority than most 
J.J. Abrams talks about the difficult task of finding the right actress to play FBI Agent Olivia Dunham in this interview held during the Fox upfront last week. I have to say that I agree wholeheartedly with the casting of Anna Torv - she completely owns this part.
One correction to that piece from SciFiWire — the Casting Agent’s name is April Webster, not Ann
April Webster was recently honored by the Casting Society of America for her achievements in casting for television and movies. She has working on a number of JJ’s projects (Alias, Lost, Six Degrees and M:i:III), and this article from Backstage.com gives insight to her experiences after three decades in the business. She talks about casting for Lost in the piece.
My favorite piece of “Did you know…” trivia related to April is that she played the part (uncredited) of Irina Derevko in the Season 1 finale of Alias, since they did not have the part cast yet
