Revealing mistake: At the start, when the security cart driven by Miley and Lilly rips through the Hannah poster, the outline of the pre-cut tears are visible. (00:02:10)
Continuity mistake: In the dressing room, before the start of the concert at the beginning, Miley tosses her sneakers, grabs her boots, takes off her green jacket and tells her father to leave the room so she can change. In the next overhead shot, as she and Lilly fuss over the makeup, Miley wears her green jacket again. (00:02:50)
Visible crew/equipment: During Lilly's sweet 16 party at Santa Monica Pier, when she is skateboarding and catches hold of Drew, in the two shots facing Lilly the reflector screen and boom mic are reflected on the helmet to Drew's left. (00:14:00)
Continuity mistake: After Blue Jeans pulls off the Hannah wig and Miley refuses to go back in the pickup truck, Miley opens her makeup case with its extendable handle facing away from Miley, but next shot she is sitting beside the case and the wig has suddenly appeared in her left hand (viewer's right) as well. (00:22:05)
Continuity mistake: After Lilly (in the Hannah wig) arrives, she and Miley enter the bedroom and Miley puts the suitcase on the chair. In following shots the suitcase has flipped over to the opposite side. (00:57:05)
Continuity mistake: When Miley does her first quick change so she can meet Travis at the restaurant, the little white purse is on her left wrist as she walks in through the door, but next shot as Miley enters it's on her right wrist. (01:07:25)
Continuity mistake: Just after the table fire incident at the dinner, "Hannah" rushes past the housekeeper in the maintenance closet and grabs her makeup case with her right hand and reaches for her "Miley" dress and boots with her left hand. Next shot the case is in her left hand and she reaches up with her right hand. (01:13:20)
Plot hole: At the concert in Crowley Corners, Miley announces that she will sing a new song she just wrote, "The Climb." Somehow the band and the backup singers all know the words and the music.
Revealing mistake: After Miley lets a truckload of walnuts roll down the street, the British reporter is having a hard time keeping his balance. At one point, both feet just barely touch the ground and it is quite obvious that he was suspended on a cable during filming.
Continuity mistake: As Hannah exits the plane in Tennessee, a man arrives in a pickup truck. In the close-up, exhaust smoke is blowing in front of the truck, but in the next shot the only smoke is coming from the tailpipe and blowing in the opposite direction.
Continuity mistake: After Miley fights with Travis at the revolving doorway, she picks up her pink suitcases and wig, and runs into the building. After she runs up some stairs with the luggage still in her hand, the next shot shows her running up more stairs only holding the wig and not the suitcases. They disappear for the rest of the scene.
Continuity mistake: When Miley Cyrus sings "Hoedown Throwdown" and shows the audience the steps for the first time, there is a back shot of her showing the audience cheering and you can see Miley remove the microphone from the stand and start to sing into it. In the next shot the microphone is back in the stand again.
Continuity mistake: When Hannah is going around in the revolving door in slow motion, where she reveals to the little girl and Travis that she is really Miley, the red suitcase is in her left hand the entire time. But, when she exits the door and is standing at the top of the steps talking to Travis, the red suitcase is suddenly in her right hand.
Continuity mistake: When Blue Jeans the horse takes off Mileys' wig it disappears from the horse's mouth, then suddenly reappears in Miley's hand.
Audio problem: When Miley and her dad arrive in Tennessee just when Jackson arrives in the truck, Robby Ray says "Tennessee", but his mouth doesn't move.
Continuity mistake: When Lilly finds Miley asleep on the roof, the flat area Miley is lying on has been painted ultramarine blue (just below the cupola) as the rest of the roof. When Travis sees the painted coop that flat area is as light colored as the vertical triangular wall beside it. (Particularly noticeable when Travis rides off.)
Chosen answer: During a concert, a lot of makeup is used to show through the bright lighting. In this case, Miley may have needed little to no makeup. Also, since Travis is shown asking for the check and Miley goes back and forth so much, it may have taken her a long time, which is why she had to run off every time she got to the restaurant after a few seconds.
