The longtime pal of Jackson, who died in June from an apparent drug overdose, wrote on Twitter Monday: "I was honored with the great privilege of seeing 'This Is It' last week. I was sworn to secrecy, but now I can let you know about it. It is the single most brilliant piece of filmmaking I have ever seen.
"It cements forever Michael's genius in every aspect of creativity," continues the actress, 77. "He cradles each note, coaxes the music to depths beyond reality. I wept from pure joy at his God given gift. There will never, ever be the likes of him again."
Taylor admits that she was so overcome by Jackson's final rehearsal footage that she had trouble finding words to describe the experience of watching the movie, which opens in theaters Wednesday. "We have this piece of film to remind us forever and ever that once there was such a man ... Michael knew how to put together every tone, every nuance to make magic. To say he was a genius seems so little. I wish my vocabulary encompassed what I feel."
Taylor urges fans of the King of Pop to see the film -- and take into consideration the messages Jackson wanted to convey with his music. "He was totally 'up to now' and the message of today in all his songs... Listen to his messages. From "Black And White", "Man in the Mirror," "We Are the World" ... we must take his words of responsibility seriously. We cannot let his life be in vain."
Taylor thinks the film should receive awards, and writes, "I truly believe this film should be nominated in every category conceivable."
