Worst Movie Mistakes: Date Night Edition (PHOTOS)

It's February, a.k.a. the month of Valentines, and what better way to enjoy some time with your loved one than by sitting in front of a warm fireplace, pulling up the computer, and reading another edition of Moviefone's Worst Movie Mistakes in History? (Well, probably lots of things! But there's got to be someone out there who would do that.)

This time around, we've compiled a list of ten of the worst movie mistakes from romance movies, including "Dirty Dancing," "Notting Hill," "Princess Bride" and "Pretty Woman."

(Once again, a big thanks to MovieMistakes.com, who in addition to helping us with this post, have a database full of ridiculously awesome and embarrassing mistakes made in feature films.)

Gallery | Worst Movie Mistakes: Date Night Edition

• "The 40-Year-Old Virgin"

  In a scene featuring a children's birthday party, having a different color balloon magically appear in place of another is totally forgivable. However, having an entire person replacing said balloon is not.

• "Clueless"

  In "Clueless," Cher and Dionne go to a crazy house party in the Valley (ugh), where the house they are at somehow adds a second story between the time they show up and the time they leave.

• "Fast Times at Ridgemont High"

  A fairly common movie mistake: Trying to shoot a "night" scene when it's very obviously daytime out. During this awkward dinner date in "Fast Times at Ridgemont High," you can see the Sun shining through the curtains.

• "About a Boy"

  Hugh Grant: He's charming, funny, dashing and can get rid of a giant stain on his shirt without having to take it off and/or wash it. Impressive!

• "Dirty Dancing"

  Check out Patrick Swayze's unbuckled belt instantly get fastened in the midst of this fight scene. Was it a -- gasp! -- "Ghost"? (Thanks, we'll be here all week.)

• "Mr. and Mrs. Smith"

  Brad Pitt and Angelina Jolie spent the majority of this movie in a battle of wits (and fists). However, most forget this magic trick, where Pitt takes his suit jacket off without taking his hands off the wheel. Beat that Angie!

• "The Wedding Planner"

  In this 2001 rom-com starring Jennifer Lopez and Matthew McConaughey, one scene features a shot of McConaughey's character holding a group of M&M's in his hand, which are all the same color. A second later, the M&M's are now different shades.

• "Run Lola Run"

  In this scene, an ambulance smashes into a giant piece of glass, which immediately shatters. However, right before it hits, you can see a charge go off underneath the glass.

• "Pretty Woman"

  In "Pretty Woman," Julia Roberts is the Hooker With a Heart of Gold. She may also have been a wizard with the trick she pulls off in this scene: going from croissant to pancake in seconds.

• "The Princess Bride"

  In "The Princess Bride," the role of Buttercup is played by actress Robin Wright, not a middle-aged stuntman with a beard.
