NEW YORK - The new FX miniseries "Fosse/Verdon" explores the lives of legendary Broadway director and choreographer Bob Fosse and his wife Gwen Verdon. The story came to life with the help of Dana Moore, a Fosse protégé who taught the actors how to do "All That Jazz" properly.

Moore first appeared in a Fosse show on Broadway in 1979.  

"I mean he wouldn't have cast me in these shows if he didn't believe in me, you know he believes in you and you just always felt like you could give more," Moore said.

Fosse brought musicals like "Chicago", "Sweet Charity", and "Pippin" to life with show stopping, jazzy choreography, a style memorialized in his semi-autobiographical film, "All That Jazz." His collaboration with Verdon was one of Broadway's legendary partnerships. He died in 1987 at the age of 60. Verdon passed away in 2000. 

"You worked and worked until you got it just...you know if you weren't turned in enough or you know you weren't in plie enough or you weren't still enough for that one moment," Moore said. 

Moore appeared in 12 Broadway shows. She was hired by the producer of "Fosse/Verdon" and the Verdon/Fosse Estate overseen by Fosse's daughter to teach his highly stylized choreography to the stars of the mini-series.

Sam Rockwell plays Fosse and Michelle Williams portrays Verdon. 

"It was very important to her that we are reconstructing this material to the purest of how it was first created...we want to teach it the way it was taught to us," Moore said. 

Moore grew up outside of Pittsburgh with dreams of Broadway. She moved to New York after high school to study at the American Ballet Theatre. She began auditioning right away. 

"Auditions were actually on Broadway stages for Broadway shows," Moore recalled.

In 1979, Fosse picked Moore to take over the role originated by Ann Reinking in Dancin'.

"I did a little combination and I was pretty shaky but he saw what they saw...so um, it was basically...really a magical moment," Moore said.  

Moore went on to appear in other Fosse shows including "Chicago" and "How to Succeed in Business".

She says she's helping to keep his legacy alive by teaching his style in workshops and master classes at the Broadway Dance Center and Steps.

"It changed my life and it informed everything that I do," Moore said.  

Moore will teach a Fosse workshop at Steps to prepare and inspire dancers for the show's premiere on April 9.
