It's that last item that led to Alien's achievement that still shocks audiences the most, regardless of how many times they've seen it: the famous chest-bursting scene. Yes, outer space had been scary before on film, but it had never been anywhere close to being this brutal and blood-soaked. The historical context and technical mastery of the scene is extraordinarily rich: Did you know the cast had no idea what the baby xenomorph looked like or how the scene would play out? Did you know that a lot of the creative team behind Alien wouldn't have been involved if Jodorowsky's ill-fated Dune adaptation hadn't been canned? Luckily, CineFix has released a video that explains all of this, and much more, in just under nine minutes:
The craziest takeaway from the video might be that screenwriter/film legend Dan O'Bannon was inspired to pen the scene after some fast food made him sick. So, the next time somebody chastises you for eating Jack in the Box, just tell them you're doing it for inspiration.
