Martha Stewart Says Her Autobiography Will 'Be Even More Revealing' Than Her Documentary: 'Watch Out'

The lifestyle icon called her new Netflix film "fine" during an interview with Jimmy Fallon on 'The Tonight Show'

Martha Stewart's recent Netflix documentary made headlines for its bombshell revelations — and there's more where that came from, she said.

When Stewart, 83, visited The Tonight Show on Wednesday, Nov. 13, she told Jimmy Fallon that she is working on an autobiography. “That’ll be even more revealing," she said, warning Fallon: “Watch out. You don’t know what I’ll say about you.”

Details of her new book have yet to be formally announced, but Stewart recently told Today that "Random House is publishing it in two years.”

"I call it an autobiography. It’s not exactly a memoir. It’s a fun book and all the wonderful, wonderful things I’ve done in my life and all the stories," she said in October.

During The Tonight Show segment, Fallon asked Stewart if she was happy with how R.J. Cutler’s Martha film turned out. (Stewart previously shared a blunt critique in the New York Times.)

“The documentary is fine,” she replied. “It left out a lot, so I’m going to go talk to them about maybe doing version two.”

“There’s a lot more to my life,” Stewart continued. “I mean, you know, I’ve lived a long time and I just thought, you know, maybe we’ve left out some stuff.”

“Good stuff,” she clarified.

Fallon pointed out that there’s some “juicy stuff” in the documentary, to which Stewart responded, “Oh, I know, but don’t say it now.”

Stewart revealed that she didn't really enjoy being interviewed for the film.

“I don’t like going to psychiatrists and talking about your feelings and all of that stuff,” she said. “And the director was so intense on delving.”

However, she acknowledged that Cutler’s technique elicited “good stuff,” adding, “He got some juice.”

The eye-opening documentary includes revelations about infidelity in Stewart's longtime marriage to ex-husband Andy and intimate details about the couple’s early relationship. It also covers her time in federal prison after she was found guilty on charges including conspiracy and obstruction of justice related to the sale of a stock.

In an interview with the New York Times published on Oct. 30, Stewart criticized various aspects of the film, which was released on the same day.

She said Cutler “used very little” material from her archive despite having had “total access."

She also took issue with footage Cutler used of her at her Bedford, N.Y., estate toward the end of the film.

“Those last scenes with me looking like a lonely old lady walking hunched over in the garden? Boy, I told him to get rid of those,” she said. “And he refused. I hate those last scenes.”

Her other complaints included the film’s “lousy” classical score (she says she requested rap music) and camera angles.

“He had three cameras on me,” Stewart said. “And he chooses to use the ugliest angle. And I told him, ‘Don’t use that angle! That’s not the nicest angle. You had three cameras. Use the other angle.’ He would not change that.”
