Ruby Sparks stars Paul Dano as Calvin Weir-Fields, a struggling novelist who after finding fame as a teenager, now has writers' block. To kickstart his creativity, his therapist (Elliot Gould) tells him he should write about someone who would love his dog the way he is, timid and slobbery. So Calvin starts writing about a young woman, Ruby Sparks, and unwittingly ends up falling in love with her, which he thinks is a problem, because she's not real.
The more he writes, the more real she becomes, until her underthings start showing up and he sees her in his apartment. He freaks out, assuming he's had some kind of mental breakdown, but soon realizes that other people can see her too, and that he controls her with his writing.
The film is in much part about loving someone for who they are and accepting all their faults. Calvin learns that trying to change someone can have costs, as the more he controls her, the less she is the woman he fell in love with, and that love is often complicated, but that's what makes it real.
