EW has learned from multiple sources that Tim Allen ("Home Improvement") is looking to stage a return to prime time -- as long as it involves the right project. "It will be huge," predicts one manager of Allen's comeback -- if and when it happens. Another source indicated that the actor is taking "a few select meetings" with writer-producers, one of whom may include Greg Daniels ("Parks & Recreation," "The Office"). Is there a chance that Allen could even join the staff of Dunder-Mifflin?
