I’m hearing Maura Tierney is in talks to take over the female lead in ABC’s new legal drama The Whole Truth. She would replace Joely Richardson, who quit the project earlier this month so she could spend more time with her family.

Last spring, Tierney herself was forced to drop out of a high-profile pilot — NBC’s Parenthood — to undergo treatment for cancer. Lauren Graham eventually replaced her.

The Whole Truth, which chronicles the building of a case from the perspective of both the defense and the prosecution, costars former Numb3rs cruncher Rob Morrow. (Reporting by Lynette Rice)
