If you saw Margot Robbie and Jaime Pressly standing side by side, you'd probably be able to work out who's who. They're both stunning, but Robbie is quite a lot younger than Pressly, and it's visible in their faces. It's only when you're watching a movie that Pressly made several years ago that you have to look twice and work out whether you're looking at her or Robbie.
Both were actually working in television roles at the same time, waiting for their big Hollywood break to come through. Pressly is fondly remembered for her appearances in 'My Name is Earl', whereas Robbie was a soap star in 'Neighbors' in her home country of Australia. If they aren't cast as mother and daughter at some point in the future, then directors and producers are really missing a trick.
