Allison Mack (born July 29, 1982) is a German-born American film and television actress who most famously starred as Chloe Sullivan on the WB/CW series Smallville, and also directed two episodes in Season Eight and Season Nine. She was the only cast other than Tom Welling (who played Clark Kent) to have appeared in every season of Smallville.

Mack was born in Preetz, West Germany to Mindy and Jonathan Mack, who is an opera singer performing there at the time. When Mack was two years old, her family moved back to the United States. She then began studying at "The Young Actors Space" located in Los Angeles when she was seven. She and co-star Kristin Kreuk (who played Lana Lang) were close friends prior to the exposure of Mack's criminal involvement in the cult NXIVM.



Mack began acting at the age of four in commercials for German Chocolate. She then went into modeling for a short period because her mother thought she "looked cute in clothes", and an old autographed picture of her as a child still lies framed on the wall of a Taco Bell restaurant across the street from Warner Bros. Studios in Burbank, California.

Mack's acting career started in 1989 in the film Police Academy 6: City Under Siege, where she played an unnamed little girl. Her other filmography includes Camp Nowhere (1994), Honey, We Shrunk Ourselves! (1997), and Eric Stoltz's directorial debut My Horrible Year! (2001), where she plays a girl having great difficulties in her life as she turns sixteen.

On the small screen, Mack made a number of appearances starting from 1989, including a short-lived sitcom Hiller and Diller in 1997-1998. Her first major TV role came in 1998 in an episode of the WB series 7th Heaven, where she gained a lot of attention playing a teenager who cut herself. In 2000, she starred as an ensemble cast in a short-lived Fox series Opposite Sex alongside Milo Ventimiglia and Chris Evans. She starred alongside Smallville co-star Sam Jones III (who played Pete Ross) in an R. L. Stine miniseries The Nightmare Room in 2002. She also guest-starred in the Australian-American comedy series Wilfred opposite Elijah Wood in 2012 and 2014, as well as series like Riese (2009-2010) and American Odyssey (2015).

In 2006 Mack provided the voice of the sister of the main character in the Warner Bros. CGI movie, The Ant Bully. Also in 2006, Allison provided the voice of a museum curator named Clea in an episode of The Batman (who bore a deliberate resemblance to Mack). In 2010, she voiced in the animated series Dirty Little Secrets.

Not only is Allison an accomplished actress, she is also a good singer and dancer. In her free time, Allison likes to go to the movies and theater, read, listen to music, and hang out with friends and family. Allison's family, her Dad (Jonathan Mack), Mom (Mindy), older brother Shannon, and little sister, Robyn, live in Southern California. Allison lives in Vancouver, British Columbia where Smallville was filmed.

Allison was set to direct an episode of Season Seven in March or April, 2008. Unfortunately, her directorial debut was canceled due to the Writers' Guild of America strike. She got a second chance at directing in Season Eight, when she directed the episode Power. And the next year directed again - this time the Season Nine episode Warrior. Also, she provided voice over for Power Girl in the animated movie adaption of the comic book Superman/Batman: Public Enemies.

NXIVM and criminal prosecution

Allison Mack and her mentor Keith Raniere, creator of NXIVM, were accused of luring women to a sex cult disguised as a self-help group and then brand them with Keith Raniere's initials. Mack was the leader of a secret group called D.O.S.[1]

On April 2018 she was arrested with charges including sex trafficking. A year later on April 8, 2019, Mack pleaded guilty to racketeering conspiracy and racketeering charges, and was scheduled for sentencing in September 2019. [2] The conviction was postponed by the court to grant sufficient time to conduct pre-sentencing investigations.

Mack married Nicki Clyne, another actress involved in NXIVM, in a sham green card marriage.
