Now available on DVD/Blu-ray is the romantic dramedy Ruby Sparks, from directors Jonathan Dayton and Valerie Faris (Little Miss Sunshine), about a once-famous novelist named Calvin (Paul Dano), who creates a beautiful fictitious character named Ruby (Zoe Kazan) that not only brings his work to life, but actually literally comes to life.  TheDVD/Blu-ray special features include Behind the Story, Real-Life Couples: Co-stars & Directors, Be Careful What You Wish For and the theatrical trailer.

During this recent exclusive phone interview with Collider, the film’s star and screenwriter Zoe Kazan talked about how writing this feature came about, when she realized that she and her real-life boyfriend Paul Dano would be playing the roles, what writing allows her that acting doesn’t, how she originally had a different ending for the story, that she always wanted to leave the reasons for Ruby’s existence unexplained, how she just finished writing the first draft of a new project, and working with Daniel Radcliffe (the Harry Potter franchise) on The F Word.  Check out what she had to say after the jump.

Here are a couple of casting notes in brief:

• Heather Graham (The Hangover) is set to star opposite Selena Gomez in the indie comedy Feed the Dog, formerly titled Parental Guidance Suggested.
• Rafe Spall (Prometheus), Megan Park (The Secret Life of the American Teenager) and Mackenzie Davis (Smashed) will join Daniel Radcliffe in The F Word, directed by Michael Dowse (Goon).

Two pieces of casting to close out the night:

• Paz Vega will play opera singer Maria Callas in Grace of Monaco, the Grace Kelly biopic led by Nicole Kidman.
• Girls scene-stealer Adam Driver will star opposite Daniel Radcliffe and Zoe Kazan in the romantic comedy The F Word.

Hit the jump for details on both projects.

A sharp, modern take on the Pygmalion myth, Ruby Sparks is the story of a novelist’s vision that inexplicably comes to life, only to prove far more complicated than even he could have imagined.  Ruby (Zoe Kazan) starts out as an idea in Calvin’s (Paul Dano) mind, but he creates her with such a strong individualistic desire to be her own person that he is ultimately forced to grow in order to accommodate her strength and evolution.  Directed by Jonathan Dayton and Valerie Faris from a first screenplay by actress and playwright Kazan, the film constantly challenges the audience as it takes an unpredictable route into fantasy, identity and the ways we invent love and how love reinvents us.

At the press day for Ruby Sparks, we sat down at a roundtable interview with Kazan and Dano to talk about what happens when a writer tries to make a relationship from his imagination work in the real world.  They told us what the experience was like bringing their characters to life on screen, how they approached the film’s most physically and emotionally challenging sequences, and why Dayton & Faris were the perfect duo to direct the film.  They also revealed their next projects including Dano’s upcoming For Ellen, Looper and Twelve Years a Slave and Kazan’s The F-Word.

Daniel Radcliffe’s current career trajectory is screaming, “I will not be Harry Potter forever!”  The actor has been taking on an admirable diversity of roles ever since hanging up his wand last year.  Earlier this year, he starred in the gothic horror flick The Woman in Black, he’s playing Allen Ginsberg in Kill Your Darlings, and several days ago we reported that he would lead the supernatural fantasy-thriller, Horns.

Today, Variety reports that Radcliffe is adding an indie romantic comedy to his slate by signing on to star opposite Zoe Kazan (Ruby Sparks) in The F Word.  Michael Dowse (Goon) will direct from a Black List script by Elan Mastai (The Samaritan), which has “Radcliffe venturing to be the first male to have a successfully platonic relationship with a girl he likes (Kazan), only to find out she’s already in a relationship.”  I have no idea what this means because I’m not exactly sure how the story is measuring success.  Is he trying to escape from the friend zone?  Is he trying to be at peace living in the friend zone?  Damn you and your vagueness, loglines.  Damn you to hell.
