'Emily Owens M.D.' Premiere: Mamie Gummer And Cast Talk New CW Show

"Emily Owens M.D." (premieres Tues., Oct. 16 at 9 p.m. ET on The CW) has been hailed the all-new "Grey's Anatomy." But the cast says there's more to it than that.

The CW series follows Mamie Gummer, the titular character herself, who is starting her medical internship; Will Collins (Justin Hartley), Emily's best friend, but possibly more, who also works with her; Cassandra Kopelson (Aja Naomi King), Emily's high school rival who resurfaces at her internship ... and has her eye on Will; Tyra Granger (Kelly McCreary), Emily's new friend and closeted lesbian due to her father being chief of surgery at the hospital; and Micah Ellis (Michael Rady), the fifth-year resident guiding the new interns through the hospital halls.

Below, the actors talk about "Grey's Anatomy" comparisons, love triangles, mastering medical jargon and more!
