In “Sparkle,” Tika Sumpter, Jordin Sparks, and Carmen Ejogo play sisters— and daughters of Whitney Houston’s character. The trio embarks on a musical journey during which their sibling bond deepens and they each find out some truths about each other.

Sumpter, Sparks, and Ejogo found that playing sisters came easily to them, especially as they bonded during the recording of the cast album. “You know that it’s real when somebody can deal with your attitude or not,” Sumpter joked. “When somebody’s like ‘What is wrong with you’. You’re like, ‘Look, this is how I feel right now,’ and they accept you.”

All three had poignant words about their on-screen mama, played by Houston in her last role. Sparks referred to her as a “mama bear,” who was “loving on us.” Each had lasting memories that they take away with them from their time with Houston that they shared with Hitfix, including the compliment she gave Sparks that she will carry with her for the rest of her life.

Ejogo shared the last scene Houston would ever film with the singer, who died in February. She shares a beautiful tale of those final moments with Houston.

We interviewed the three males leads in the movie as well. That piece will go up later this week.
