"In the beginning, it was supposed to be Dan Hedaya who got sucked out into space. His character, General Martin Perez, was originally set to exit Alien: Resurrection in spectacularly bloody fashion – his entire body ejected, limb by limb, through a tennis ball-sized hole in the space ship, Auriga. Effects company Amalgamated Dynamics, Inc, spent several weeks in 1996 solving the problem of having a body pulled apart realistically by the vacuum of space. Test footage released by ADI shows the painstaking process of researching and testing practical means of creating Hedaya’s death scene, which would have concluded with his character’s screaming head stripped of its skin until only a gaping skull remained. The results were almost comically grotesque and almost mesmerising to watch – so mesmerising, in fact, that Alien: Resurrection director Jean-Pierre Jeunet eventually decided that such a violent demise was more fitting for his movie’s most formidably villain, the Newborn, and not a relatively minor character. And so it was that the process of designing and testing began once again – this time on the practicalities of having a giant alien’s stomach rip open and its guts spill out on the floor before its skull shatters into countless tiny pieces."
