When you don't know who you are or what you want to do, and you have no real intention of doing what your family wants you to do, and then you decide you have to do something you have no idea you can do, what should you do? First, avoid thinking about it. Lie to your loved ones a little. Then, write a movie about it. So far, so good. But how do you know if your life is entertaining enough to be a movie? If Judd Apatow tells you it is, that's a start. Standup-turned-leading man Kumail Nanjiani puts a face on immigration, religion, racism, family and ultimately, growing up in The Big Sick. Coming to the U.S. from Karachi, he found a career and a woman he loved, then nearly lost her to a mysterious illness and his own uncertainty. It's an uncommon story he's somehow made completely relatable. In the process, he's given us one more reason to embrace our differences: They're funny.
