Universal initially set a budget of $10 million, with a modest $200,000 for "creature effects," which at the time was more than the studio had ever allocated to a monster film. Filming was scheduled to be completed within 98 days. Universals production studios estimated that it would require at least $17 million before marketing and other costs, as the plan involved more set construction, including external sets and a large set piece for the original scripted death of Bennings, which was estimated to cost $1.5 million alone. As storyboarding and designs were finalized, the crew estimated they would need at least $750,000 for creature effects, a figure Universal executives agreed to after seeing the number of workers employed under Rob Bottin, the special make-up effects designer. Associate producer Larry Franco was responsible for making the budget work for the film; he cut the filming schedule by a third, eliminated the exterior sets for on-site shooting, and removed Benningss more extravagant death scene. Cohen suggested reusing the destroyed American camp as the ruined Norwegian camp, saving a further $250,000. When filming began in August, The Thing had a budget of $11.4 million, and indirect costs brought it to $14 million. The effects budget eventually ran over by $1.5 million, forcing the elimination of some scenes, including Naulss confrontation of a creature dubbed the "box Thing". By the end of production, Carpenter had to make a personal appeal to executive Ned Tanen for $100,000 to complete a simplified version of the Blair-Thing. The final cost was $12.4 million, and overhead costs brought it to $15 million.. How many more millions of dollars did The Thing cost to make compared to how much it was budgeted for?
