Murder Mystery centers on a New York City cop, Sandler, and his wife, Aniston, who find themselves prime suspects in the murder of an elderly billionaire while vacationing in Europe. The film reunites the pair, who played love interests in 2011's Just Go With It.
A source recently told ET, meanwhile, that Aniston was starting to dip her toes back in the dating pool after her breakup from Theroux.
After Aniston and Theroux ended things, ET's source said the Friends star "really relied on her friends to get her through the tough times." "During that time, she was able to heal and be comfortable with dating again," the source explained.
"Jennifer has never felt she needed a man, but she loves love," the source continued. "Jennifer is casually dating, but right now nothing serious. She is just having fun, seeing where things go."
