6. Tina Fey and Amy Poehler
Before they made a lot of people laugh in “Saturday Night Live”, Tina Fey and Amy Poehler were comedians full of passion that show off their improvisational abilities in the Chicago’s iO Theater class.
The two later start writing for the comedy sketch series “Saturday Night Live”. Their first cooperation was after they starred at “Mean Girls”. They next appeared in comedies such as, “Baby Mama”, “Sisters”, and “Wine Country”. After those films, Poehler continued to work with Fey. She even said about Fey – “I think that Tina and I are chosen sisters”.
