Gupta, who exec produces with David E. Kelley, attended a bash the cabler threw Thursday at WeHo’s Boa Steakhouse to celebrate the show’s Feb. 4 premiere.

Kelley’s longtime director Bill D’Elia said he will try to break “Mornings” out from the medical pack by shooting it with darker tones than most hospital-based shows. And the reason?

“I really want the blood to pop,” he said.
