Trio of pilots find helmers

'24's' Jon Cassar among helmers landing new gigs

"24" helmer/exec producer Jon Cassar has been tapped to direct the CBS drama pilot "Washington Field," and Michael Fresco is set to helm ABC's untitled Dave Hemingson dramedy pilot.

Meanwhile, Adam Bernstein will direct NBC's drama pilot "Mercy," which Gretchen Berg and Aaron Harberts have joined as exec producers.

Cassar will tackle the CBS Par-produced "Field," about FBI agents called together for critical cases.

Fresco will helm a retooled version of the Hemingson project, first picked up to pilot last season. Four actors from the original pilot -- star Matt Long, Ben Lawson, Norbert Leo Butz and Tina Major¬ino -- are staying on.

The UMS-produced "Mercy" is a comedic drama about three nurses. ICM-repped Berg and Harberts will serve as co-showrunners alongside creator-exec producer Liz Heldens. Bernstein directed the pilots for NBC's "30 Rock" and CBS' "Worst Week."
