The two actors play a married couple in the movie, which follows an aspiring writer who gains fame when he finds an old manuscript and passes it off as his own.
The pair avoided any appearance of their reported off-screen romance by staying apart from one another while posing for photos and giving interviews to support the film. Saldana did affectionately touch Cooper as they passed in a hallway, though.
Both had been to Sundance before, where snow fell throughout the festival and the weather dipped into the teens. Still, Saldana maintained her fashionista edge.
