10 Things You Probably Didn't Know About The Cloverfield Franchise
7. Motion Sickness Warnings
After Blair Witch's success in the late 1990's, the found footage genre began to rise in popularity and is now a common theme in the horror genre of today. In these films, the action is captured by the characters themselves before their demise at the end - thus earning the 'found footage' style as their devices (usually an old camcorder) are then retrieved and compiled, making it look like it really happened.
Abrams and Matt Reeves were keen on following the same style for the first movie, referencing the archived videos of the 2001 terror attack on New York. Much like Blair Witch and others in this genre, the actors were given the cameras themselves and a lot of the final cut is their own captured footage.
The characters run from street to building, dodging explosions and debris as the alien attacks the city above them, causing the chaotic and shaky movement throughout.
Because of this, cinemas received complaints as movie goers experienced overwhelming travel sickness, and often would throw up whilst watching. Subsequently, the production company included a warning at the beginning.
