Goofs

When Katherine drives into the parking spot at the pizza place, she parks correctly in between the lines but when she exits the vehicle, her car is parked diagonally across two spaces.

When Palmer meets with the "wife" at the hotel bar, her hair is curly. But when they say goodbye in front of the hotel a few minutes later, she has almost fully straight hair.

At the lagoon-swimming scene, Katherine's shirt goes from wet to dry and back to wet, before she had even been in the water.

When Danny, Maggie, and Michael are getting pizza when he's convincing them to be his "fake" children, a man in a yellow plaid shirt is behind Danny. In one shot, he gets out of the booth and is gone; in the next shot, he's back and gets up and leaves the table again.

At the beginning of the hula competition there are six women. A moment later there are only five women.

When Katherine is confessing to Devlin at the end of the movie, she says she drives a Honda, but she gets out of a Chevrolet at JD McFunnigan's.

When Palmer and Dolph are having dinner alone and the girl comes running in yelling that her sheep needs help, she refers to it as "he" several times. She asks for a vet and again says "he is dying". When Dolph goes to help, he milks the sheep and tells it to go and have babies.

Devlin claims that her husband made all his money suing the Dodgers after being hit by a foul ball. That is not legal. There is the law "Assumption of Risk" which goes into effect at baseball games. If someone gets hit by a ball, they are not allowed to sue because of that law. He would not have been able to sue, let alone get money from the Dodgers.

When Danny complains about his back hurting from sleeping on the beach, Katherine asks him when he's going to strengthen his spine. "Seriously, Flomax. You gotta work out more than once a month."

Flomax is used to treat symptoms of enlarged prostate by relaxing muscles in the prostate/bladder and has nothing to do with strengthening the spine.

Irritable Bowel Syndrome is not a disease as mentioned by Danny. It is a syndrome, hence the name.

While sitting at the bar with Devlin at the end of the film, Katherine should have seen Danny behind her long before he showed up because after she said she might be in love with him, she looked back towards Ian.

Ways these shenanigans could have been prevented, aside from telling the truth.

• Danny could have not had the ring in the first place.
• Katherine could have said the kids were from a previous marriage.
• If Danny didn't want to get married, he could have said, either the divorce wasn't finalized yet, or they have no marriage license.

At around 58 mins Danny tells Maggie "And I love you, my little British crumpet!" In England the word crumpet in the context provided would mean hot or sexy woman--inappropriate from father to "daughter," whatever her age, but especially when she's grade-school age.

When they are in the room with the patient who had an implant break, crew/equipment is visible in the window to the right.

At the end, when Danny points to Brian as he plays the bass guitar, his beard (as Danny mentioned early on in the movie) supposedly wiggles; the string used to make this happen is visible.

At about 56 minutes into it, Danny throws his cousin Eddie to the ground before running from the wild pig. The pig proceeds to chew on Eddie's back. You can clearly see the peanut butter the crew smeared onto the back of his shirt to get the pig to chew on him.

Smart and Final's house brand, First Street, can be seen in some background shots, but there are no Smart and Final stores in Hawaii.

Supposedly Palmer could tell when Danny was lying, but after the first lie she detected, she didn't detect or question any of his following lies.

When Danny is teaching Michael how to swim, Katherine and Palmer show up and start watching. Maggie yells to her little brother, "Keep going, Michael, don't give up!" They are supposed to be using their fake names in front of Palmer, so Maggie should have called him "Bart" instead of "Michael", and/or Palmer should have asked why she was calling him Michael.

When Katherine is trying on high heels and stumbles, she says it's because she hasn't worn high heels in awhile. However, in an earlier scene she is wearing high heels.

Danny tells Katherine that he got Maggie to eat three pieces of deep-dish pizza. The pizza they ate was hand-tossed. Deep-dish pizza at Pizza Hut is served in a pan. Their pizza was on a wood serving tray and obviously thinner than pan pizza.

When Palmer is talking to the concierge about her wedding she spots Katherine trying to sneak by and calls out "Devlin" and Katherine responds.
