Wright, 52, told NBC's Today show that beyond filming she "didn't know" the 58-year-old actor who plays her on-screen husband, despite working closely with him for five seasons of the popular Netflix drama.
Several accusations of sexual misconduct have been levelled at Spacey since October, whenStar Trek: Discoverystar Anthony Rapp claimed Spacey had attempted to seduce him at a party in the Eighties when Rapp was 14 years old. Spaceyapologised for the alleged incident, but said he did not recall what may have been drunken behaviour.
Last week, Scotland Yard confirmed that Spacey was being investigatedby its Child Abuse and Sexual Offences Command officers over allegations raised by six men.
In a clip from the NBC interview, which will be shown in full later today, broadcaster Savannah Guthrie asks Wright, "Was there any kind of red flag, or anything which made you think this was possible?"
