 Giger was unhappy with some elements he found to bear similarity with other movies , particularly the Alien franchise . At one point he sent a fax to Mancuso finding five similarities : a " chestburster " ( as Sil giving birth echoed the infant Alien breaking out of its host 's chest ) , the creature having a punching tongue ( Giger at first wanted Sil 's tongue to be composed of barbed hooks ) , a cocoon , the use of flame throwers , and having Giger as the creature designer . A great point of contention was the ending , which Giger considered derivative from the climaxes from both Alien 3 and Terminator 2 : Judgment Day . The designer felt that horror films frequently held some final confrontation with fire , which he considered old @-@ fashioned and linked to medieval witch trials . He sent some ideas for the climax to the producers , with them accepting to have Sil 's ultimate death occurring by headshot .
