Allison Mack: Hollywood actor with key role in abusive Nxivm sex cult

The Smallville star was sentenced to three years in prison on Wednesday. How did she fall into the service of such a group?

Allison Mack, the actor best known for her starring role in the series Smallville, presented a very different look to the woman who'd arrived at the same Brooklyn courthouse in early 2018 to be arraigned on charges she manipulated women into becoming sexual slaves within the Nxivm self-empowerment group.

Back then, she was confident and smartly dressed - the picture of a successful Hollywood actor. On Wednesday, she was head bowed, her blonde hair obscuring her face, wearing a simple dress resembling a penitent's sack-cloth.
