Having A Ball Playing Lucy

After Joe Biden voiced his support for gay marriage ahead of President Barack Obama, there was only one thing for the vice president to do: apologize. Biden did that on Wednesday in the Oval Office. He apologized shortly before Obama sat for a hastily arranged interview in which he told the public he supported gay marriage. Biden had made similar comments on Sunday without permission from the White House. His remarks thrust gay marriage into the political spotlight and focused fresh attention on what Obama has called "evolving" views on gay marriage. (AP Photo/Charles Dharapak) / Charles Dharapak

Actress Rachel York will be filling some big shoes in her first starring television role.

This Sunday, she brings the life of legendary comedienne and television star Lucille Ball to the small screen in the CBS drama, "Lucy."

The television movie is based on the true story of the celebrated, complex, passionate and tumultuous relationship between Lucille Ball (York) and Desi Arnaz (Danny Pino).

"Lucy" also takes a behind-the-scenes look at the creation of one of television's most beloved shows, "I Love Lucy."

York says this is the first movie that tells Ball's ambitions in life from a young age. York picks up the role from age 22. She describes playing the part as a journey that leads into the real passionate love story of Ball and Arnaz.

To research her part, York says that she read and viewed everything about Lucy Ball. However, York says she walked a fine line of performing and imitating Ball.

The actress says she hopes the audience learns something they didn't know about Ball and Arnaz.

York recently completed a national tour of "Kiss Me, Kate." Her theater credits include "City of Angels," "Les Miserables," "The Scarlet Pimpernel," "Little Me" and "Victor/Victoria" on-Broadway and "Putting it Together," "Where's Dick?" "Lost in the Stars," "They Shoot Horses, Don't They?" and "A Minor Incident" off-Broadway.

Her film credits include "Billy Bathgate" and "Dead Center." York's television credits include "Diagnosis Murder" on the Network, as well as "Frasier," "Reba," "Spin City," Arli$$," "The Naked Truth," "L.A. Law" and the television movies "Second Honeymoon" on the Network, "Taking the Heat" and "Au Pair II."
