In the interim between Ferguson's departure in December 2014 and James Corden's premiere on March 23, 2015, CBS scheduled a number of guest hosts to helm the program. In this transitional period, the show continued to be co-produced by Worldwide Pants and the staff was mostly made up of holdovers from Ferguson's era. The executive producer remained Peter Lassally, however the show was produced by newcomer Jeff Stilson.
