Women who accused actor Dustin Hoffman of sexual assault have penned a thank-you letter to comedian and late night TV host John Oliver for "challenging" the film star.

"We want to thank you for confronting Dustin Hoffman. While the questions you asked may not have led to the constructive conversation you hoped for, the fact that you asked them all is what matters most," the letter, posted on Twitter, reads.

"Many men listen to and believe women when we recount our experiences of sexual harassment and assault," it continues. "But few men put themselves at risk — socially or professionally — to have uncomfortable conversations with other men."

"Women can continue to tell our stories, but ultimately, change will depend on men reflecting on their own behavior and challenging other men to do the same," it concludes.

The letter was signed by seven women: Anna Graham Hunter (the woman who posted the letter on Twitter), Wendy Riss Gatsiounis, Kathryn Rosseter, Melissa Kester, Cori Thomas and two women "who have chosen to remain anonymous."

On Tuesday, Oliver said he'd "tried and failed" to address the mounting accusations against Hoffman in a now-viral interview for the 20th anniversary of the film Wag The Dog.

"It became such a big story, but it became about my questions rather than Hoffman’s answers,” Oliver told Sky One's Russell Howard. “The questions weren’t particularly remarkable, but his answers were … not great. It didn’t really go anywhere constructive, so the whole thing just made me feel sad."
