EXCLUSIVE: Fox has handed a late pilot order to Weekends at Bellevue, a medical drama from former ER writer-producer Lisa Zwerling and BermanBraun. The project, centered on a psychiatrist in charge of the weekend shift of Bellevue Hospital psychiatric unit, was originally set up at NBC and UMS earlier this season. After the network recently passed on the script, it was taken to Fox. UMS, which produces Fox’s hit drama House, will stay on as the studio. Weekends at Bellevue is based on Dr. Julie Holland’s memoir about her nine-year stint as the weekend physician in charge of the psychiatric emergency room at the oldest public hospital in the United States whose name has become synonymous with insanity. Zwerling, Gail Berman, Lloyd Braun and Gene Stein are executive producing.
