17 Again (2009) - 94 mistakes

Continuity: After Mike and Ned fight with lightsabers, when they are in the kitchen Mike's wedding ring moves from his left hand to his right hand and back again, between shots.

Visible crew/equipment: Before the start of the last basketball game, when Ned calls out, "Jane!" for the third time in the shot facing him as he tries to pass someone, the actors' green T-mark and three other tape marks - one yellow and two red - are visible on the floor ahead of Ned. (Visible on DVD fullscreen.)

Continuity: When Mike walks into Health class, Mrs. Dell's lectern and stool (upon which the basket of condoms and another basket sit) stand directly in front of the chalkboard, but funny how they are both conveniently gone when Mike knocks Stan to the floor, in front of that chalkboard.

Continuity: On the bridge, when Mike topples into the water headfirst, the distinctive treads on the heels/soles of his shoes, as well as the light colored brand logo on the heels, are visible. After the newly transformed Mike appears at Ned's home wearing the same clothing, when Ned pulls the rug out from under Mike, his shoes' soles are completely different.

Visible crew/equipment: In the opening shot of Ned and Mike in the kitchen, with frozen veggie ice-packs on their assorted injuries, just before it cuts to Ned staring at Mike, the actor's orange tape mark is visible under his feet as he is sitting on the stool. (Visible on DVD fullscreen.)

Continuity: In the shot just after "Mark" tells Scarlet about Alex and the new girlfriend, Nicole (at the victory party), we see Jane's car driving down the block (towards the camera) headed to Ned's home and there are multiple black tire tracks (burned rubber) on the road at the intersection. After a close-up of Jane and Ned in the car discussing 'Halo', it cuts back to the intersection as the teenagers cut them off, and the tire tracks are gone.

Continuity: Before the '89 basketball game begins, Mike is on the court with the cheerleaders and when he pulls off his blue snap warm-up pants he is wearing the grey uniform shorts and jersey. However, after Mike poses in the close-up, he is wearing the blue warm-up pants again in the next shot from behind the cheerleaders - note his jersey number "0", which is visible between the cheerleaders.

Visible crew/equipment: When Mike slams Stan down to the floor in Health class, the grey padded protective gear that Mike wears under his pants is visible as his shirt moves up.

Continuity: In the ice cream shop, when Mike picks up the unplugged jack for Maggie's earbuds, he holds the jack pointed up with its cord grasped within his closed palm, but next shot the cord is dangling free under the unplugged jack.

Continuity: After Naomi and Scarlet head into the house to work on getting Scarlet back on the market, when Mike is driving in the rain the rearview mirror is gone, but it reappears when Mike runs toward the 'janitor' who disappeared from the bridge.

Continuity: Before the '89 basketball game, in the first shot of Mike joining the cheerleaders on court, the bare chested guy wearing a Native American headdress is dancing beside the free throw lane, near the backboard. In the next shot that guy is now dancing half a court away, in front of the stairs opposite center circle (note the "Lets win" poster). The same thing happens a few shots later.

Continuity: At the start in the gym, when Mike is alone shooting baskets (before the team photo) he is standing at the center of the 3-point line, but in each of the overhead close-ups of the hoop we see Mike's reflection in the backboard (top right) and he is standing closer to the hoop, on the free throw line - note the dark free throw lane. (Only visible on DVD widescreen.)

Continuity: After their fight, when Mike and Ned are in Ned's kitchen with frozen veggie 'ice-packs' over their assorted injuries, Mike has a bag of frozen peas that keeps turning around, facing the opposite way, repeatedly.

Continuity: The morning after Mike's party at Ned's house, when Ned finishes vacuuming the rug in the overhead shot the wood floor immediately surrounding the rug is clean, but in the next shot there is a mess right beside the rug, which would have been visible in the previous shot had it been there.

Continuity: In 1989, when Ned walks in, he takes off his brown dungeon-master jacket and puts on a blue sweater. In the first shot, he has it fully on, but when he walks toward the basketball team he is putting the right sleeve on again.

Continuity: When Ned and Mike encounter the street guard, whilst in the yellow car rushing to the court, the rear-view mirror changes position.

Continuity: During Mike's victory party, at one point you can see Mike in the back holding up a lightsaber. In the next shot when he says "Don't touch the toys," it is now down by his torso.

Other: In the scene when its 1989, there is a man visible wearing a Paramore shirt in the crowd. Paramore formed in 2004. I don't think there was another band in the 80s called Paramore.

Continuity: When Maggie is crying about being dumped, her makeup changes from the time Mike first came by her, where it was purple, to the end where it is black.

Continuity: During Mike's first class (before Maggie walks in), when he is on the cell with Scarlet, who is asking where he is, a cheerleader sits behind Mike and places her left arm up with her hand at her chin and her right arm is down. Next shot, when she asks Mike if he would consider a 10th grader, now it is her right arm that is up and her left arm is down.
