Some improvisation was encouraged. Weaver discussed tweaks to her character with Cameron on set, believing she understood how Ripley would act. Her line "Get away from her, you bitch!" had to be filmed in one take due to the tight schedule remaining, and the actress thought she had messed it up. Paxton believed he was not good at improvisation, and discussed ideas with Cameron before filming. One of his signature lines, "Game over man, game over", originated when Paxton developed a backstory for Hudson in which he was trained on simulators. Henn found it hard to act afraid of the aliens (since she was fond of the actors in the suits), and imagined a dog was chasing her. Other cast members spent time with Henn between scenes, including Weaver and Paxton (who would color or craft things with her). Biehn said he and Paxton spent much of their free time together. Weaver gave a bouquet of flowers to each actor on the day their death scene was filmed and gave Reiser a bouquet of dead flowers. Despite the difficulties during filming, Fox was satisfied with the daily footage; "Aliens" was delivered on time and on budget.
