Chloë Grace Moretz
Chloë Grace Moretz was only 8 years old when she played Chelsea Lutz, the youngest of the Lutz daughters in 2005's The Amityville Horror. The original Amityville Horror (1979) is regarded as a staple of horror cinema, but the 2005 remake featuring both Moretz and Ryan Reynolds was surprisingly well-received. Moretz's breakthrough came in 2010 when she received critical acclaim for her performance as Hit-Girl in Kick-Ass.
Ben Affleck
Ben Affleck is one of the most celebrated actors of the modern era, but he wasn't exactly at the top of his game in Buffy the Vampire Slayer (1992). "Apparently, I'm so bad in that movie," Ben said, looking back on the role of Basketball Player #10. "I had one line. It was 'Take it,' I think."
