Visible crew/equipment: In the shot of Michael Douglas pouring a drink at the back of the plane, you can see the boom mike overhead.

Audio problem: When Steve is thanking Melissa for marrying Mark, the bride turns out to be Angela. Angela knocks Steve to the floor and grabs a gun from under her wedding dress. You can hear the sound of a hammer cocking but the gun turns out to be a hammerless automatic.

Visible crew/equipment: In the first plane scene, you see the toy plane take off, if you look at the first shot of it coming off the ground, you can see a shadow of a person and the headphones with the mic over the mouth.

Continuity: In the final wedding scene in the tent, both the father of the bride and the father of the groom walk in looking fresh and dry, not looking at all like they had just hopped off a jetski and been hit with a large wave.

Factual error: When Michael Douglas and the girl have just taken off in the plane, someone shoots at them with a machine gun. But the person is behind the aircraft, not at the side and so it would be impossible for the bullets to crack the side window.

Revealing: Steve's partner Angela has straight hair, but the stuntlady who doubles her in the city car ride has curly hair.

Continuity: Near the end at the wedding scene Michael Douglas is seen arriving wearing a tie that has the world's greatest knot in my opinion. Throughout the next few minutes you will see the knot get worse and then back to the original.

Factual error: When Michael Douglas and his son (and others) are tied up in chairs, they pretend to fight and cut each other's bonds. The son says something like, "The one time my father came to Cub Scouts, I earned the Covert Action Merit Badge." But there are no Merit Badges in Cub Scouts; they are a part of the older Boy Scout program. (There isn't a "Covert Action" Merit Badge either, but that helped the movie along, so it's okay.)
