It seems that when PornHub saw Kumail Nanjiani’s original tweet, they went looking for the illegal upload.
Though I did find Zootopia and Back to the Future if you’d like to watch those.
Although, they apparently had some difficulty finding the movie as well, which led to a fairly terrible thing for people to have to experience on Christmas.
Unfortunately, a cursory glance at the site, which I did entirely for work purposes, stop looking at me like that, makes it appear that The Big Sick has been removed from PornHub, so if you were hoping to check it out for free, you’ve lost your chance.
