Emma Stone, Joaquin Phoenix visit park for Woody Allen film

NEWPORT, R.I., July 31 (UPI) -- Emma Stone and Joaquin Phoenix were spotted together on set earlier this week.

The 25-year-old actress and 39-year-old actor visited a park in Newport, R.I. to film scenes for Woody Allen's new, untitled movie. Stone sported a backpack and held what appeared to be a textbook and folder, suggesting her character may be a student. Phoenix may portray a professor, and was seen with a briefcase in mid-July when the film began production.

Little is known about the plot and characters, but executive producer Ron Chezid has said the movie is "a murder mystery, set on a college campus." Parker Posey and Jamie Blackley are also attached to star.

Stone recently finished Allen's Magic in the Moonlight, which opened in limited release July 25. The actress stars as the potentially fraudulent psychic Sophie, with Colin Firth as love interest and magician Stanley. She will next appear in Birdman on October 17.
