Simon Cowell may not be the only American Idol vet on the outs. According to insiders, Nigel Lythgoe—who has not been secretive about his desire to recast the entire roster of judges—will revive his role as executive producer of American Idol. With Cowell's (voluntary) departure, top management has set its sights on shaking things up even further to resuscitate ratings. According to the Hollywood Reporter, Simon Fuller and Fox may do more than just bring in Lythgoe—they may do away with the entire judges’ panel. According to insiders, Lythgoe will continue to judge and executive produce Fox's So You Think You Can Dance.
