Kurt Fuller has signed on for the cast of David E. Kelley's hourlong NBC pilot Legally Mad and has also signed on for a three-episode arc on the CW's Supernatural.

According to The Hollywood Reporter, Assaf Cohen has been added to USA Network's 90-minute pilot Operating Instructions.

The Warner Bros. TV-produced Legally Mad centers on Brady Hamm (Charity Wakefield), a twentysomething woman who takes a job at a law firm run by her father (Hugh Bonneville). Fuller will play Lou Peable, an attorney in the throes of a midlife crisis.

On Supernatural, also from WBTV, Fuller will play a corporate executive who secretly has supernatural authority.

Operating Instructions centers on Lt. Rachel Scott (Emily Rose), a former Marine who returns from a tour as a Navy surgeon to become head of trauma surgery at a military hospital. Cohen will play eager staff anesthesiologist Eli Funston, who alternately is frustrated by and in awe of Rachel.
