Karen Gillan holds on to a huge bottle of water while on the set of Not Another Happy Ending in Glasgow, Scotland, on Friday (July 20).

The 24-year-old actress dished to TotalFilm about her new movie role, “I play a successful writer called Jane Lockhart, who writes best when she’s unhappy. She’s feeling good about her life and therefore can’t write her next novel, so her publisher Tom goes on a secret mission to make her unhappy to get the book written.”

The flick, set to debut in 2013, is set to be directed by John McKay and costars Stanley Weber and Henry Ian Cusick.
