CinemaSins is back at it, this time revealing everything wrong with Ridley Scott's 1979 Alien movie.
Alien kicked off the franchise starring Sigourney Weaver and brought in $104,931,801 worldwide.
While that amount may sound low compared to today's standards, bear in mind Alien only had a budget of around $11 milllion.
Ridley Scott continues the Alien franchise with Alien: Covenant, which is out in 2017.
