People who go to watch a Fifty Shades movie typically expect the rough and tumble action to play out on the screen, not in the seats.
But according to police, one female fan became so enraged at a man for talking during a Valentine's Day showing of Fifty Shades Darker, she allegedly assaulted him in an attempt to shut him up.
Police are now appealing for any witnesses to the incident, which occurred about 10.15pm on February 14 at Hoyts Woden.
They described the woman as 5'7" tall, approximately 40 years old and with short brown hair.
Anyone with information should contact Crime Stoppers on 1800 333 000.
