Neither IMDb or Box Office Mojo have Hush on IFC's list of distributed films, but this article from Deadline states they did handle the US distribution:

EXCLUSIVE:WME has signed Mark Tonderai, who directed House At The End Of The Street, the romantic thriller that stars Jennifer Lawrence, Max Theriot and Elisabeth Shue and just got picked up for 2012 release by Relativity Media. The film is Tonderai’s follow-up to his directing debut Hush, which created buzz in the UK, was nominated for a British Independent Film Award, and made the courtship of the director a competitive one among Hollywood agencies. WME will rep him for film and TV. Hush was acquired for U.S. distribution by IFC. Tonderai has started Shona Films with partner Zoe Stewart, and they are developing several projects including an adaptation of the Roger Smith book Wake Up Dead, and they are also working on The Kill Team, a drama about the attempted siege of Sierra Leone in 2002. Tonderai is managed by Brian Lutz and repped in the UK by Josh Varney.
