NEW YORK (AP) - Lifetime is going back to the 1990s with a TV movie on the Saturday morning show "Saved By the Bell." The network said Thursday that its film, "The Unauthorized Saved By the Bell Story," is being made in Vancouver and will premiere on Labor Day. It will examine the life of young unknown actors in Hollywood trying to maintain the clean image of their characters while growing up amid the temptations of show business. The same person who cast the original series will handle that role for the TV movie. Dylan Everett of "Degrassi: The Next Generation" is in line to play the ringleader role of Mark-Paul Gosselaar, and "Screech" is being handled by Sam Kindseth of "Shameless."
