Cameron turned in the finished script in February 1985, hours before a Hollywood writer's strike. The script was well-received, but Fox executives (including chairman Barry Diller) were concerned about the budget. Fox estimated the cost as close to $35million, but Hurd said it would be closer to $15.5million. Diller offered $12million, prompting Cameron and Hurd to quit the project. Gordon negotiated with Diller until he relented, and Cameron and Hurd returned. In April 1985, conflict turned to the cast; Fox did not want Weaver to return because they expected her to demand a large salary. Cameron and Hurd were insistent Weaver return as the solo star; Fox refused, saying they would damage the studio's negotiating power with Weaver's agent. Cameron and Hurd again left the project, marrying and going on a honeymoon. When they returned, the "Aliens" project was ready to move forward. Cameron credited Gordon with "Aliens" being greenlit.
