Actress Julianne Moore was on Cantor Fitzgerald's trading floor Wednesday to participate in the firm's annual Charity Day. She spoke with CNBC's "Squawk on the Street" about both her charity work and her most famous role among Wall Street traders.
Moore's charity, Children's Health Fund, offers medical care to underserved children. She will be answering phone calls and taking donations as part of the drive.
The star said that traders recognize for her most for her role in the 1998 movie "The Big Lebowski."
