Woody Allen's Daughter -- 'He Sexually Assaulted Me' ... Hollywood Should Stop Praising Him

Woody Allen's daughter claims the director sexually assaulted her as a child ... on multiple occasions ... and says Hollywood should be ASHAMED of itself for praising him at the Academy Awards.

In an open letter published in the New York Times, Dylan Farrow goes into horrific detail about the alleged abuse suffered at the hands of the man who adopted her.

"When I was seven years old, Woody Allen took me by the hand and led me into a dim, closet-like attic on the second floor of our house. He told me to lay on my stomach and play with my brother’s electric train set. Then he sexually assaulted me."

In the letter, Farrow says Allen's abuse didn't end there:

"I didn’t like it when he would stick his thumb in my mouth. I didn’t like it when I had to get in bed with him under the sheets when he was in his underwear. I didn’t like it when he would place his head in my naked lap and breathe in and breathe out."

Farrow claims she would try to hide from Allen, but he would always find her.

As she got older, Farrow claims the abuse took a huge toll on her mental health -- and she was so messed up, she developed an eating disorder and even cut herself.

FYI -- back in 1992, Dylan's mother, Mia Farrow, reportedly accused Allen of sexually assaulting Dylan ... and he was investigated ... but prosecutors decided not to pursue charges because Dylan was too "fragile" to endure a trial.

At the time, Allen denied the allegations ... saying Mia was simply bitter about his affair with Soon-Yi Farrow Previn (another adopted daughter ... who he later married.)

In her letter, Dylan then goes after several Hollywood stars who have praised Allen throughout the years:

"What if it had been your child, Cate Blanchett? Louis CK? Alec Baldwin? What if it had been you, Emma Stone? Or you, Scarlett Johansson? You knew me when I was a little girl, Diane Keaton. Have you forgotten me?"

"Woody Allen is a living testament to the way our society fails the survivors of sexual assault and abuse."
