Lifetime's "I Will Always Love You: The Whitney Houston Story" faces opposition from the late singer's other family member. Whitney Houston's mother Cissy is pleading the cable network to cancel the biopic that will focus on Houston's tumultuous relationship with former husband Bobby Brown.

"Lifetime has chosen to go ahead with the movie about Whitney in spite of my family's objections," Cissy told Entertainment Tonight. "In the two years since Whitney's death, many people have stepped forward to speak about their close relationship with her."

She continued, "I find it difficult to believe people who knew and supposedly loved her would participate in a movie about her done by folks who didn't know her. We are exhausted by the continuing misinformation and comments offered by people who did not know her. Please please let her rest."

The biopic's director Angela Bassett said she did reach out to Houston's family before the movie went into production. "Of course we're not going to do the movie and not say anything to them," Bassett said. "We paid our respects and let the conversation be had, just to get their okay."

Bassett, who is making her directorial debut, said she would respect Houston in the movie. "I have such regard for both Whitney's and Bobby's amazing talents and accomplishments; and I feel a responsibility in the telling of their story. Their humanity and bond fascinates us all. I'm beyond excited to have this opportunity to go behind the camera and into their world," she said.

Earlier this month, Houston's daughter Bobbi Kristina Brown blasted Bassett for not considering her to play her mother in the biopic although she had uttered her desire to take up the role. YaYa DaCosta was cast in the main role instead.
