Kazan: Sparks flew on new film
Zoe Kazan has confessed that things got a bit tense between her and boyfriend Paul Dano while making their new movie Ruby Sparks.
The actors, who have been dating for five years, play a couple in the first flushes of a new relationship in the film, which Zoe also wrote.
She said: "This movie is about the beginning stages of a relationship - moving out of the honeymoon period but starting with the very first meeting - and by the time we made this movie, Paul and I had been together for four years, so we just sort of had to remember what it was like at the start.
"We did a lot of very silly exercises like touching each other's skin and we made this pact not to kiss for the first two weeks of filming so that our first kiss in the film could be sort of our first kiss in a little while."
But she added: "I think that's one of the reasons we could get very cranky with each other coming home from work - for a couple of weeks, there was no smooching!"
