Glen A. Larson - He is headed straight for permanent, full time retirement. If the "Manimal" series gets made at all, it will be made by other people with zero participation from Glen A. Larson.
Bryan Singer - Bryan Singer's very next project (immediately after his already forgotten "H+" webisode series on www.youtube.com) will be a fairly mundane low budget movie (around $30 million) where he will be one of the co-producers. Four other co-producers will be listed above his name in the closing credits of this movie (in order of seniority.) This movie won't receive any fanfare, will have extremely limited theatrical distribution, and will go to DVD very quickly and quietly. The big budget, Sci-Fi spectacle days of Bryan Singer in Hollywood are long gone.
1. If "Jack The Giant Killer" gets made at all, Bryan Singer will have nothing to do with it.
2. If "Battlestar Galactica" gets made at all, Bryan Singer will have nothing to do with it.
