The Cosby Show's Phylicia Rashad has joined NBC's Dr. Jeckyll and Mr. Hyde drama, Do No Harm.

The show is a modern Dr. Jeckyll and Mr. Hyde drama that revolves around Jeffrey Kohl (Steven Pasquale), a brilliant neurosurgeon who wrestles with his dangerous alter-ego that threatens to wreak havoc on his personal and processional life.

The actress will portray Dr. Vanessa Young, the chief of surgery and Jeffrey's boss. She joins Alana De La Garza, Mousa Kraish, Michael Esper and Ruta Gedmintas in the drama.

This project is still in development.
