The Tony Awards, theatre’s highest honor for Broadway productions, will be held on Sunday, and there are five nominees for featured actresses in a play.

Katy Sullivan made theater history with her performance in the drama "Cost of Living." Born with no legs, Sullivan is the first performer with such a disability to appear in a Broadway show.

"There were people that were like - until I came out at curtain call on my prosthetics - they were trying to figure out what the trick was. And it's not a trick. It's authentic," says Sullivan, who played a quadriplegic character often at odds with her estranged husband who is her caregiver.

Sullivan's co-star, Kara Young, received her second consecutive Tony nomination for portraying a caregiver who develops feelings for the patient in her care.

"I think caregivers... we don't give them enough respect. We don't give them enough love. Because that's a very challenging job" says Young.

Crystal Lucas-Perry played multiple roles in the short-lived satire "Ain't No Mo,'” earning her a nomination. Like "Cost of Living," "Ain't No Mo'" is also nominated for Best New Play.

Completing the featured actress nominees are Miriam Silverman for the revival of Lorraine Hansberry's "The Sign in Sidney Brustein's Window," and Nikki Crawford in "Fat Ham," the comedic send-up of "Hamlet" set as a modern-day family cookout.
