Pike, 36, is nominated for an Oscar for playing the lead role of Amy Dunne in David Fincher‘s Gone Girl, an adaptation of Gillian Flynn‘s bestseller. One of the most memorable scenes from the film features Pike slicing the throat of Neil Patrick Harris‘s character, Desi. In order to feel prepared, Pike wanted to know how much force would be required to do such a thing.

“I always get worried about anything physical, like the action sequences. Neil Patrick Harris and I had to do a violent scene. If you’re going to do something like that, you have to do it with a certain degree of accuracy,” Pike told Collider. “I had no idea how much force you needed to slice someone’s throat. I actually went to a butcher and asked them if they wouldn’t mind me just using a box cutter on a pig carcass, just to understand what it would be like. They let me do it, so anyone buying meat that day would have seen me behind the counter, with serious intent, finding out the mechanics of doing that. That was purely for research purposes.”

Pike’s preparation didn’t end with her trip to the butcher. After a long day of practicing the intimate lead-up scene with Harris, Pike still felt underprepared. On her way home from set, she picked up what would serve as a body double for further practice at home.

“I was driving home one night and I went into CVS and I found this Dora The Explorer doll. But she was only this big and well, I thought I could kind of use this but she wasn’t tall enough. She had to be as tall as Neil Patrick Harris,” Pike told Jimmy Fallon on The Tonight Show. “So I taped her to a post and then practiced the scene at home by the swimming pool.If any neighbors were looking outside they would have seen me do highly inappropriate things with this Dora The Explorer doll.”

Pike is up against Julianne Moore (Still Alice), Reese Witherspoon (Wild), Felicity Jones (The Theory of Everything) and Marion Cotillard (Two Days, One Night) in the Best Actress category at the 2015 Academy Awards. The awards ceremony will air Sunday, Feb. 22 on ABC at, starting at 7/6c.
