Time recently released its “100 Most Influential People List” which divides some of the world’s most creative, innovative, and inspiring individuals into five categories: Titans, Pioneers, Artists, Leaders, and Icons. This year, Reese Witherspoon, Bradley Cooper, Kevin Hart, Emma Watson, John Oliver, and more landed spots on the coveted list, accompanied by a special blurb written by a famous fan.

Here’s what celebrities like Jack Nicholson, Oprah Winfrey, Martha Stewart, Tilda Swinton, Amy Poehler, and others had to say about their “Most Influential” person. The full list is available here.

Kanye West: “But Kanye does think. Constantly. About everything. And he wants everybody else to do the same: to engage, question, push boundaries. Now that he’s a pop-culture juggernaut, he has the platform to achieve just that. He’s not afraid of being judged or ridiculed in the process.” – Elon Musk

Lorne Michaels: “Hard to think of anyone more skilled at discovering extraordinary comedic performers, who have gone on to become household names in their own right. It’s no wonder SNL‘s takes on current events have made headlines for 40 years.” – Jack Nicholson

Lee Daniels: “And now with the runaway success of Fox’s Empire, his seductive new hip-hop drama, it seems like there is nothing Lee can’t do. He is taking us all on an uninhibited, bodacious ride, bringing in new viewers each week at a pace that is unheard of in today’s television landscape.” – Oprah Winfrey

Kim Kardashian: “Despite the flamboyance, the self-aggrandizement and the self-promotion (Kim set out to break the Internet by baring her bum in an extraordinary photograph), Kim comes across as an enviable big sister in a clan where everyone seems to love one another. Are they indeed today’s Brady Bunch?” – Martha Stewart

Laverne Cox: “She’s done so many amazing things—not just acting on Orange Is the New Black but also loving herself enough to share her story with the world. She’s a pioneer for our community.” – Jazz Jennings

Amy Schumer: “She’s the one most likely to be on your side when the bullies circle in. That’s her face, there, that one pushing in to save you, elbowing them out of the way. She’s the one who misses nothing: who buys no bullsh-t, fitted with a radar as keen as a rabbiting spaniel.” – Tilda Swinton

Chris Pratt: “He is a real man in a sea of ciphers, a good father and friend, and one naturally funny dude. Pratt may spend the next few years riding horses or chasing comets, but he can land a joke with a natural ease that most people spend a lifetime trying to achieve.” – Amy Poehler

Taylor Swift: “Along with her staggering list of accomplishments, perhaps the most exciting thing about Taylor is that she’s just getting started with what she plans to mine from her fierce, curious, boundlessly talented and beautiful heart. Also, it doesn’t hurt that she named her cat after me.” – Mariska Hargitay
