By now, everyone knows more than they could ever want about the disaster of “Grace of Monaco,” the Nicole Kidman film once potentially primed for a Best Picture Oscar … that wound up as a Lifetime movie on Memorial Day.

[How ‘Grace of Monaco’ went from prestige Oscar bait to Lifetime movie]

If you don’t follow showbiz behind-the-scenes, the gist: The movie, starring Kidman as Grace Kelly in 1962 as she struggled with leaving her acting career and embracing her role as wife to Prince Rainier III of Monaco, famously bombed at the Cannes Film Festival last year. It was mired in public fights between super-producer Harvey Weinstein and French director Olivier Dahan, who had very different visions of the movie. Throw in the fact that the Monaco royal family condemned the film, and you’ve got quite a trainwreck, even for Hollywood standards.

Screenwriter Arash Amel was mighty displeased with the two final edits of the movie, neither of which he says honors his original script. He promised that he would live-tweet his own “Grace of Monaco” commentary when the movie aired on Lifetime Monday night, given that it skipped theaters and went straight to cable.

True to his word, Amel didn’t hold back. “The purpose of this live tweet is to correct the record, an explanation, an apology and most of all a bit of light hearted fun,” he wrote, calling it his DVD commentary. Here are some of the highlights from Amel’s very entertaining hours of tweets:

* He used behind-the-scenes stills from the movie to illustrate his unhappiness.

* He really hated the music.

The score was reportedly always a problem, and Amel wasn’t thrilled that it played over tense scenes of Grace Kelly and Prince Rainier (Tim Roth), especially as they argued over what would happen if she went back and filmed another movie for Alfred Hitchcock. (She previously starred in “Dial M For Murder,” “Rear Window” and “To Catch a Thief.”) Amel spoke out about the music during multiple scenes:

* We learned this was the third version of the movie.

There was an edit from Dahan that showed at Cannes, and another by Weinstein that apparently would have been shown in theaters. And then the one on Lifetime.

* Amel was unhappy that the movie tonally resembled “Vertigo.”

Weinstein made this point as well.

* Random facts about production.

Between disappearances and near-fights, Amel struck up a friendship with former “Gilmore Girls” and “Heroes” star Milo Ventimiglia, who played Kelly’s spokesperson.

* Okay, Amel did say SOME nice things.

* But he still thought the ending was wrong.

The film continued on, even after Kidman made an inspiring speech in front of world leaders and it appeared to be the end.

* Overall, though, it was an educational experience on many levels.
