Nurith NupurDiana Muldaur as Dr. Katherine Pulaski
The makers didn’t renew this actors contract after the first run of the Next Generation, and subsequently, the character of Dr. Beverly Crusher was mysteriously disappeared and was replaced by Dr. Pulaski. To this day no one knows what happened to the character and where it went but the actors playing the role went onto have an amazing career in L.A. Law.
