Upfront season has begun, when the networks announce their programming for fall. First to bat is NBC, which is retaining the genre hit Heroes and giving it a spin-off, Origins, which will run in the same time slot in the off season (whenever that may be.) Among the brand-new shows is the Bionic Woman remake and Journeyman, in which Rome’s Kevin McKidd as a time-traveling reported, and Chuck, about a computer geek who becomes a government agent. Check out NBC.com for previews of the new shows.
