▲Ryder was once mid-sentence with a casting director when when they stopped her and told her that she shouldn't be an actress, that she wasn't nearly pretty enough, and that she should go back to where she came from. We wouldn't have enjoyed so many great films if she'd listened!

▲Worried that your family isn't famous enough? Don't!

▲In the '70s, Stallone had very little money and was struggling to get by with his minor roles.
