The 64-year-old Canadian screenwriter was sued in December by film publicist Haleigh Breest for allegedly raping her in 2013 at his apartment after a movie premiere.
However, Haggis denied the claims and now, three more women have come forward with sexual misconduct allegation with one accusing that Haggis forced her to perform oral sex then raping her, reports the Deadline.
Another woman claimed that in 2015, the 'The Third Person' director tried to forcibly kiss her.
In his defence, Haggis previously said he's used to defending himself against "false allegations" because he is a notable critic of Scientology.
Haggis is writer and director of 2004's 'Crash', which won Academy Awards for best picture and best original screenplay.
He also earned an Oscars nod for best-adapted screenplay for 'Million Dollar Baby'. (ANI)
