I suppose I should start with the horror movies that got an, often inferior, American remake:

• The Wicker Man (1973)
• Suspiria (1977)
• Nightwatch (1994)
• Funny Games (1997)
• [•REC] (2007) - Quarantine
• Martyrs (2008)
• Låt den rätte komma in (2008) - Let The Right One In
• Somos lo que hay (2010) - We Are What We Are
• Ich seh, Ich seh (2014) - Goodnight Mommy/Mummy
