20 Things You Somehow Missed In The Social Network
15. Aaron Sorkin's Cameo
You'll probably be aware that the movie was written to Oscar-winning success by the great Aaron Sorkin, though you'd be forgiven for not knowing what he looks like - or at least, not noticing his cameo in the film.
Sorkin appears for around 30 seconds as one of the ad executives who Mark and Eduardo (Andrew Garfield) attempt to get onboard to invest in the website, though due to Mark goofing off with a glottal stop noise, he doesn't seem much impressed.
Apparently Sorkin had no intention of having a cameo role in the film, and only performed the part at the insistence of Fincher, who was very eager for him to do it.
