When a trailer misrepresents the movie it advertises, when you view the actual movie, you see the trailer has nothing to do with the narrative, characters or plot. You are a victim of trailer fraud.
当一个预告片不能代表它所宣传的影片，观众在实际观看影片的时候发现预告片跟影片的内容、人物或情节均不符合，那么观众就是被预告片给骗了，成了预告片陷阱的受害者。
When a trailer to a movie shows something different than the movie is actually about, or when a trailer just shows the best parts of the movie, and when you see it, it’s a let down. Then this is called trailer fraud.
当预告片和实际放映的影片内容不同，或者预告片只显示了影片的精华部分，而观众看到影片的时候却大失所望，那么这就可以叫做是“预告片陷阱”。
