Originally there were live lobsters in the tank, so once Hardy let Fleischer know what he was going to do, the crew had to evict the lobsters and replace them with plastic lobsters so that the actor wouldn’t be clawed.
It’s also worth noting that this tank wasn’t empty of living creatures when Tom Hardy decided to take a dip.
None of this was supposed to happen as Venom was initially conceived, but thanks to Hardy’s thinking, the scene became much funnier and more memorable.
CinemaBlend’s own Sean O’Connell recently had the opportunity to speak with Ruben Fleischer ahead of Venom’s release, and during the interview, Fleischer went into detail on how Tom Hardy escalated Eddie Brock’s freakout upon hearing the symbiote’s voice for the first time in a restaurant to straight up dunking himself into a lobster tank full of water.
