* EnforcedMethodActing: [[http://www.slasherama.com/features/mylittleeye.html According to this interview with director Marc Evans,]] the temperature was intentionally left below zero, and Stephen O'Reilly's (Danny) grandfather really did die during filming.
* PlayingAgainstType: Two examples.
** First off, Bradley Cooper, at that point in time, played nice guy roles such as the aforementioned Will. Here, he portrays Travis. [[spoiler:He ends up being one of the main people in The Company. To put it lightly, they certainly were the ones who did all the twists listed above.]]
** Secondly, Sean Cw Johnson, as mentioned above, plays nice guy/heroic characters and is most famous for playing Carter Grayson the Red Lightspeed Ranger. Here, he doesn't seem to portray against type at first, as Matt is a nice guy despite sharing a creepy story in the beginning of the film. [[spoiler:That is, until he suffocates Charlie and beheads Rex. Oh, and he also attempts to kill Emma. Also, in a deleted scene, Matt [[DrivenToSuicide drives Danny to commit suicide.]]]]
