A great part of the film was filmed in Russia, where nearly all the crew spoke only Russian. Elisha Cuthbert says that only a handful of the cast were there from America, and formed a tight-knit group since they spoke no Russian
The initial advertising campaign for Captivity featured a multi-paneled poster. The first panel was labeled "Abduction," featuring actress Elisha Cuthbert appearing petrified, her mouth covered by a black gloved hand. The second panel was labeled "Confinement" and showed Cuthbert behind a chain-link fence with a bloody thumb poking through. The third was labeled "Torture" and featured Cuthbert on her back, her face hidden within a white cast and red tubes going up her nose. The fourth panel was labeled "Termination" and featured what appeared to be a limp body hanging over a table. The poster was placed on several billboards across Los Angeles, causing a significant uproar and resulting in many complaints. Distributor Lionsgate - who were not involved in the film's advertising campaign and claimed to know nothing of the poster in question before the posters were distributed - and producer After Dark Films ultimately decided to remove the controversial poster from the advertising campaign and took the billboards down.
Near the end of the film when Jennifer grabs the shotgun and points it at her captor, there are no shot shells on the spot on top of the gun, only empty holes. When Gary grabs it and points it at her, red shot gun shells are clearly visible on top of the gun.
(at around 40 mins) While on the telephone at the beginning a boom microphone is visible tracking along with Elisha Cuthbert's actions in the mirror behind her.
In the acid shower torture scene, the clothes of Jennifer Tree are changing twice. In the 8th close-up she's wearing all of a sudden a different dress (the dress from the teeth pulling scene). After that it's changing back to the original dress.
What are the differences between the theatrical version and the unrated edition? How about the original Thriller Version?

The unrated cut of the movie adds more than 3 minutes of futher material to the film. A detailed comparison between both versions can be found here.During the production phase the direction of the movie was completely changed. First planned as a classic thriller the movie was turned into a 'torture flick' due to the success of movies like Hostel or the SAW series. The first cut of the movie, the Thriller Version, got released in Spain only and is a real oddity.
