Last week’s Must List Live covered Lost, Wolverine, and American Idol — jeeze, is anything even left? Fear not! Our trusty Dalton Ross and Jessica Shaw will guide us through the best next week has to offer, and as always, they’ll have a surprise celebrity guest also weighing in. Can you guess next week’s A-list must-lister?

  • He or she has graced the cover of EW
  • He or she has played both royalty and a Neo-Nazi
  • His or her current star-making turn is as a character from Riverside, Iowa

Put on yer thinkin’ caps and get guessing! See you on Monday for the big reveal. (We’ll see you before then, too, but…also on Monday.)
