Screenwriter live-tweets Nicole Kidman flop Grace of Monaco with amazing revelations

The screenwriter behind Nicole Kidman's 2014 film flop Grace Of Monaco has exacted revenge on the film's director who ripped apart his script.

Arash Amel took to Twitter on Sunday night during the movie's TV premiere on the Lifetime network in the US.

Amel took aim at director Olivier Dahan and others as he used the broadcast to highlight the film's mistakes.

He began his live commentary by writing: "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 added: "I'll keep people storming off set, three-hour shooting days and missing sets for my memoirs."

Among Amel's revelations was that the film's unit production manager vanished just a few weeks into filming and he was never seen again.

He also challenged viewers by asking: "Anyone know what's going on?"

But Amel stopped short of criticising the cast and singled out actress Parker Posey, who played the character of Madge.

"Parker Posey has never been more underused in the history of cinema".

He also had kind words for Kidman, who plays Princess Grace in the film.

"Nicole was the best. Terrific to work with on every level."

The film premiered at the 2014 Cannes Film Festival and was savaged by critics and condemned by members of Monaco's royal family.

Btw, our Unit Production Manager vanished in week 3 or 4. Never seen again. #GOMFacts

This final speech was untouched in the US cut. This and the dinner scene are the only two scenes that survived in tact from script #GOMFacts
