Second Kevin Spacey sexual assault allegation surfaces

A US filmmaker has become the second person to allege sexual misconduct by Hollywood actor Kevin Spacey as House of Cards, the TV series he starred in, continues to topple.

In an exclusive interview with Radar Online, Tony Montana claims the American Beauty star groped his genitalia while he ordered a drink at a bar in Los Angeles in 2003.

"I went up to order a drink and Kevin came up to me and put his arm around me," Montana, then in his 30s, told Radar.

"He was telling me to come with him, to leave the bar. He put his hand on my crotch forcefully and grabbed my whole package."

Spacey is then alleged to have said, "This designates ownership" as he held Montana's genitals - to which Montana responded by pushing his hand off and walking away. He says he was then followed to the bathroom, and had to tell Spacey's friend to take him home to escape his advances.

Montana says he had only told therapists about the incident before now, and struggled with PTSD for six months after it is alleged to have occurred.

He told Radar he felt compelled to come forward after reading Anthony Rapp's account of molestation at the hands of Spacey while just 14-years-old.

Meanwhile the Netflix series Spacey stars in, House of Cards, has fallen further into disarray with the news that production for its sixth and final season has ground to a complete halt.

It was reported on Tuesday (NZ time) that the sixth season would be the show's last, but now even that has been shrouded in doubt.

A joint statement from the production companies involved announced they have suspended creation of the series indefinitely while they "review the current situation and address concerns of the cast and crew".

With the future of the series quickly unravelling, discussion around potential spinoffs starring House of Cards' lead actress Robin Wright, who plays Claire Underwood in the show, and supporting actor Michael Kelly in his role as Doug Stamper.
