The original prologue to Sony's Venom was originally much more extraterrestrial than seen in the final film.
Director Ruben Fleischer revealed that the opening scene to the film very nearly began on the titular symbiote's homeworld before it was decided to keep the origins of the alien lifeforms more mysterious, opting to simply show a spacecraft from the Life Foundation returning to Earth with the symbiotes on board.
"The beginning of the movie was a hard one. Like, how much do we want to tell the backstory? There was a version where there was a planet crawling with tons of symbiotes that were collected and taken back to Earth by the Life Foundation," explained Fleischer in an interview with Cinema Blend. "My instinct was it would be better to keep it more mysterious and just know that they've retrieved something from space. We don't know exactly by what means or how."
In the final film, Jenny Slate's character mentions to Tom Hardy's Eddie Brock that the nefarious company recovered the symbiotes from a comet and brought them to Earth, leaving the wider glimpse into the extraterrestrial society and its connection to the Life Foundation more enigmatic.
