During the December 2009 filming, on-set rumors indicated that the show could begin filming its regular series episodes within a matter of weeks, pending network approval. At the January 2010 Television Critics Association Press Tour, NBC's Angela Bromstad and Jeff Gaspin said that the pilot would be reviewed by executives and that "Rex" could become either a fast-track program airing in Spring 2010 (to help cover NBC's scheduling nightmare regarding the 2010 Tonight Show conflict) or it could be an early Fall 2010 program. During the early months of 2010, there were at least two test screenings for the pilot in April, one at Universal Parks &amp; Resorts in Orlando, Florida and another at a screening room in Las Vegas, Nevada.
