When "90210" premieres on The CW this fall, it will be a cooler, more provocative version of the original series, "Beverly Hills, 90210." ET has your first look at the new cast, including ROB ESTES, LORI LOUGHLIN, JESSICA WALTER, SHENAE GRIMES, TRISTAN WILDS, ANNALYNNE McCORD, MICHAEL STEGER, DUSTIN MILLIGAN and RYAN EGGOLD.

JENNIE GARTH will be making special guest star appearances as her original character, Kelly Taylor.

"90210," like the original, centers on the Mills family (in lieu of the Walshes), which moves from the Midwest to Beverly Hills.

But this time around, the patriarch, Harry Mills (Estes), is a Beverly Hills High alumnus who moved after graduation to Kansas, but must return to the infamous zip code when his alcoholic 1970s movie star mom (Walter) begins to spiral downward. Along for the ride -- Harry's wife, Celia (Loughlin), a former Olympic medalist; biological daughter Annie (Grimes); and adopted son Dixon (Wilds).
