Cuckoo is a 2009 British thriller film starring Laura Fraser, Richard E. Grant, Tamsin Greig, Antonia Bernath and Adam F, set in London, UK.

The film tells the story of student Polly (Laura Fraser) who begins to think she is going mad as she starts to hear unexplained sounds.

Cuckoo was shot on location in December 2007 and January 2008 in London and Norwich, and in a studio built in a disused grain warehouse in Yarmouth.

[8] In a four-star Den of Geek review, Doralba Picerno wrote that Cuckoo was "a little gem of a movie ... which will keep you engrossed for its duration and get you to do a lot of thinking about it afterwards.
