"Woah, just saw this press about WW having problems," Jenkins tweeted Friday. "Are they serious? This is some made up bs right here. Made up! Produce a source, anyone. [...] You can't because it's entirely false."
Written under a pseudonym by someone who claims to be a former Warner Bros. employee, the letter slams the studio not only for the way it handled layoffs in 2014, but also for films ranging from "Man of Steel" and "The Man From U.N.C.L.E." to "Batman v Superman: Dawn of Justice" and "Suicide Squad."
"What are you even doing?" the letter states. "I wish to God you were forced to live out of a car until you made a #1 movie of the year. Maybe 'Wonder Woman' wouldn't be such a mess. Don't try to hide behind the great trailer. People inside are already confirming it's another mess."
In her response, Jenkins, who also directed the acclaimed 2003 crime drama "Monster," accused the anonymous writer of "trying to spread some serious misinfo."
"Isn't until you are intimately involved in these things that you realize how totally false these rumors can," she tweeted. "Let me reassure you ... Zero about the movie we are making has been called a mess by anyone in the know. Fact. Real lasso of truth, time, will reveal that letter to be false soon enough. But lame something so transparent in its agenda gets traction."
Opening June 2, 2017, "Wonder Woman" stars Gal Gadot, Chris Pine, Connie Nielsen, Robin Wright, Lucy Davis, Lisa Loven Kongsli, Danny Huston, Elena Anaya, Ewen Bremner, SaÃ¯d Taghmaoui and David Thewlis.
