Fox has given early greenlights to dramas “Primary” and “American Crime,” continuing this season’s trend toward pre-upfront pickups.“American Crime” is the only pilot produced by Warner Bros. TV-based Jerry Bruckheimer Television this season. Skein revolves around a group of high-profile defense attorneys. Cast includes “Alias” star Victor Garber. “Primary,” from 20th Century Fox TV, is a “Mr. and Mrs. Smith”-type hour about hostage negotiators. Project, which stars Ron Livingston, had been given the go-ahead to start staffing and building sets Thursday, making a pickup almost a formality. Fox last week ordered the drama “Vanished” and laffer “‘Til Death,” while NBC has given the official go-ahead to three drama projects for next season.
