"I'm now convinced that I'm a doctor. I mean, if someone says they have a pain, I'm like, 'Well, that's your spleen.'"

In this quote, Olivia Wilde is expressing her self-confidence in her abilities as an actor to convincingly depict a medical professional. She is stating that she has actually become so immersed in her function that she now truly thinks she is a physician. This appears in her response to someone pointing out a discomfort, as she instantly delves into a medical mindset and identifies the source of the pain as the spleen. This reveals her dedication to her craft and her capability to completely embody a character. It also highlights the importance of research and preparation in producing a believable performance.
