An actress with a small role in Woody Allen's upcoming movie, A Rainy Day in New York, has donated her salary to Hollywood's Time's Up legal defence fund – which gives support to those who have experienced sexual harassment, assault, or abuse in the workplace.

Rebecca Hall agreed to appear in the film seven months before allegations of sexual misconduct involving Harvey Weinstein first broke and said in an Instagram post that she regretted her decision and “wouldn't make the same one today”.

Hall worked with Allen on 2008's Vicky Cristina Barcelona, for which she received a Golden Globe nomination for Best Actress, and said that she has “always been grateful” to him for the breakout role.

However, having read through Dylan Farrow's statements on Allen's alleged sexual abuse she had a change of heart.

She wrote: “My actions have made another woman feel silenced and dismissed. That is not something that sits easily with me in the current or indeed any moment, and I am profoundly sorry. I regret this decision and wouldn’t make the same one today.”

A Rainy Day in New York, starring Timothee Chalamet, Jude Law and Elle Fanning, has already put its actors in the spotlight after 22-year-old Chalamet was criticised for wearing a Time's Up pin to the Golden Globes.

“It's gonna be really important for me to talk about that,” Chalamet said in an interview with CNN on Thursday when asked about his decision to work with Allen.

“I hesitate to talk about it right now because what I say is only gonna anger people. So when that film comes out, if it comes out, that's gonna be really important to talk about, but that's not the time right now.”

The movie, reportedly a romcom about a middle-aged man (Law), who has a sexual relationship with a 15-year-old girl (Fanning), was set to be released in 2018.
