Ashton Kutcher
Though Ashton became a star because of That 70’s Show, on which he played the role of Michael Kelso. It shot him to fame, but he still got on the top 100 worst actors list because critics felt his character never evolved with time.
Mandy Moore
Critics feel that Mandy’s performance in Cursed was her worst acting moment because she wasn’t up to speed with the production. In fact, people said she was so bad that some of her scenes were deleted and reshot with Mya Harrison in the role!
