In the film, Gerard Butler's character appears as a guest on The Late Late Show with Craig Ferguson (2005). Butler and Craig Ferguson are good friends in real life, and the former has been a guest on the real show several times.

Gerard Butler, in an effort to thoroughly understand the "man's man" in American society, went behind the scenes of Adam Carolla's namesake podcast to observe him.

The film was shipped to theaters under the code name "Helpful Advice."

Was featured on episode 344 of the comedy podcast How Did This Get Made live from Scotland.

Kevin Connolly's character Jim is supposed to be 5 feet and 8 and a half inches. In real life, Connelly is actually 5 feet 5 inches tall.

Continuity

When Mike and Abby take off in the hot air balloon, the background shot shows the balloon high in the air (at least above the height of other balloons). However, the next shot of Mike trying to get off shows the balloon nowhere near that far off the ground.

When Abby meets Mike in the hotel lobby, a girl in a blue dress is behind Mike. When Abby enters from the other direction, the same girl in a blue dress is behind her.

When Mike helps Abby talk to Colin on the phone, a green light appears when Colin is on hold. As the scene switches back and forth, the light turns red at one point, then back to green. Colin was on hold the entire time.

When she is in the hot air balloon speaking at first, the camera is above her head, when Mike comes to the balloon to jump in, the video camera is at her shoulder level. When they continue their conversation, the camera is mounted back up above her head.

When the boss is in the meeting room about to introduce Mike, the picture frames of Larry and Georgia in the background change places repeatedly between shots.



Incorrectly regarded as goofs

When Mike makes a comment about an "Irish Craig Ferguson," he's making fun of Abby's awful attempt to mimic Craig's Scottish accent; he's not saying Craig Ferguson is Irish.



Revealing mistakes

When Mike and Abby are on camera on the hot-air balloon, it is secured to the basket and balloon lines. When they move around, the basket and lines move with them while the camera remains still.

When Abby is on the "kiss cam" at the baseball game, the Devils are ahead 4-1. The scoreboard doesn't change when the batter hits a run-scoring single.

The warning sign on the back entrance to the news stage is on the inside of the door instead of the outside.



Audio/visual unsynchronized

When Abby gets out of the car at the LA hotel, the sentences she mumbles aren't the same words you hear.

When Abby calls Colin the first time and Mike hangs up on him there is a dial tone on Colin's line but the cordless Mike is holding is not disconnected yet. There shouldn't be a dial tone because his phone is still connected.



Errors in geography

The balloon festival is given to be in or near Sacramento. Sacramento law prohibits hot air balloons from flying around the city due to a fire hazard. It is one of a few cities in the world to have this law. The festival actually takes place in Temecula, over 450 miles to the south of Sacramento.



Character error

Various cast members refer to the Sacramento station morning show as "a network" or "network program." It appears to be a local TV station.

Mike's show "The Ugly Truth" airs on the local channel 83. Mike asks if Abby is calling from Europe. It's impossible for Europe to receive the channel that airs his show.
