TV Guide Online has learned that Semper Fi, the troubled NBC military drama from producer Steven Spielberg, will go into production this fall for a tentative midseason debut. The highly-touted DreamWorks series — which nearly was reduced to a two-hour TV-movie after being felled by a slew of production hurdles — stars Scott Bairstow (Party of Five), Sharon Exler (10 Things I Hate About You) and Steve Burton (General Hospital).
