Production on Empire was temporarily suspended on Jan. 30 by 20th Century Fox Television and Fox Entertainment.
The shutdown of the Chicago-based series was not immediately related to the alleged attack on Empire actor Jussie Smollett.
According to E! News, production of both Empire and the legal drama Proven Innocent, has been temporarily halted due to the arctic temperatures in Chicago.

Fox has also increased security around the Empire production in Chicago, according to reports.
Smollett was attacked on Jan. 29 after arriving in Chicago from New York.
According to the Chicago police department, a 36-year-old male was allegedly approached by two unknown offenders who “gained his attention by yelling out racial and homophobic slurs towards him.”

Chicago police say they’ve reviewed hundreds of hours of footage from downtown surveillance cameras but haven’t found footage yet of the alleged attack on Smollett.
The department said in a news release late Tuesday that detectives reviewed footage from privately-owned cameras near where Smollett says he was attacked and will broaden their search by reviewing footage from traffic cameras and public bus cameras.
Smollett told police he was walking downtown near the Chicago River at around 2 a.m. on Tuesday when two masked men hurled racial and homophobic slurs at him, beat him, threw an “unknown substance” on him and put a rope around his neck.
The 36-year-old actor, who is black and gay and plays the gay character Jamal Lyon on the Fox television show, took himself to Northwestern Memorial Hospital for treatment.
