In scenes where the jury is dining, Splenda brand sweetener packets are visible on the table. Splenda was not introduced until 1999.
The jury is sequestered at a hotel with a huge "InterContinental" sign over the front door. While it's accurate that the jury was held at a hotel of that chain, that spelling is more recent. In 1994, the chain styled its name with a hyphen, "Inter-Continental."
The hotel the jury is staying in has doorknobs on the room doors with a large black circle on them. These are RFID door locks, which weren't seen in hotels until at least the mid-2000s.
