Allen's lawyer, studio and publicist weighed in on Farrow's open letter, published online Saturday by The New York Times, in which she claimed that in 1992 at the family's Connecticut home, Allen led her to a "dim, closet-like attic" and then sexually assaulted her. Farrow didn't specify Allen's actions but described other abusive behavior.
The movie director's publicist, Leslee Dart, said in an email Sunday that Allen has read Farrow's letter.
"Mr. Allen has read the article and found it untrue and disgraceful," Dart said, signaling that Allen would fight the claims dating back to Allen's tempestuous relationship with actress Mia Farrow in the early 1990s.
Elkan Abramowitz, Allen's lawyer, said: "It is tragic that after 20 years a story engineered by a vengeful lover resurfaces after it was fully vetted and rejected by independent authorities. The one to blame for Dylan's distress is neither Dylan nor Woody Allen."
Allen was investigated on child molestation claims for the 1992 accusation but was never charged.
Dylan Farrow's open letter didn't urge renewed legal action but a retrial for Allen in the court of public opinion.
But on Sunday, Sony Pictures Classics, which regularly distributes Allen's films including his latest, "Blue Jasmine," urged caution in any rush to judgment.
"This is a very complicated situation and a tragedy for everyone involved," the company said in a statement. "Mr. Allen has never been charged in relationship to any of this, and therefore deserves our presumption of innocence."
Ronan Farrow, the son of Allen and Mia Farrow (though she has said ex-husband Frank Sinatra could be the father), said Sunday on Twitter: "I love and support my sister and think her words speak for themselves."
Alec Baldwin, who has starred in Allen films including "Blue Jasmine," was among those Farrow singled out in her letter, asking, "What if it had been your child ...?"
Baldwin responded on Twitter to those demanding a comment from him: "You are mistaken if you think there is a place for me, or any outsider, in this family's issue."
Dylan Farrow's most detailed account of the 1992 encounter returned the spotlight to the original police investigation of Allen. The handling of the investigation was criticized after Litchfield County State Attorney Frank S. Maco said at a news conference that he believed there was "probable cause" to charge Allen but decided against prosecution partly to avoid a traumatic trial for the young girl.
A disciplinary panel found that Maco may have prejudiced the ongoing custody fight between Allen and Mia Farrow by making an accusation without formal charges.
Months before Maco's news conference, a team of child abuse specialists from Yale-New Haven Hospital were brought in to examine the case and concluded that the child had not been molested.
Maco, who retired in 2003, told The Associated Press on Sunday that the statute of limitations on Dylan Farrow's accusations ran out at least 15 years ago. He said he hopes Farrow was able to watch his news conference and read his statement about his decision not to prosecute Allen.
"I hope she has access to that statement, to know what I did and why I did it," Maco said. "I hope she finds some peace and solace at this time."
A spokesman for the Connecticut Division of Criminal Justice said Sunday that the prosecutor's office won't re-examine the case unless the office is asked.
The 1992 allegation came shortly after Allen became involved with Mia Farrow's adopted daughter, Soon-Yi Previn. Allen, then in his mid-50s, was not the adoptive father of Previn, who was about 19 at the time. The two married in 1997 and have two adopted daughters.
