While waiting for the family movie “Frozen” to start in a Florida cinema, the audience— kids, toddlers and their shocked parents alike—got the surprise of their (young) lives when sexually graphic clips appeared in what was apparently a mistaken insertion during a delay in the showing of the feature film.

“Frozen” is a PG-rated movie from Disney and one of the top draws during Thanksgiving weekend in the United States.

Meanwhile, the trailer that was shown unintentionally was from the film “Nymphomaniac” by controversial Danish director Lars von Trier. The movie is a drama about a woman which recounts her sexual history in graphic detail.

A movie-goer, Lynn Greene, was with her grandchildren when the unfortunate incident happened.

“It seemed like forever when you’re trying to, you know, cover a little guy’s eyes,” Greene said in an interview with My Fox Tampa Bay. "I didn't have enough hands to cover his ears too and he got the sound down real good."

The movie also drew a bit of controversy when it released a trailer in YouTube early November and was taken down by the video hosting site because of the explicit content.

“Nymphomaniac” features Uma Thurman, Charlotte Gainsbourg, Stellan Skarsgard, Christian Slater, Jamie Bell and Shia LaBeouf, among other stars. The highly-anticipated, sexually-charged flick is set for an initial release on Christmas Day 2013 in Copenhagen, Denmark.
