Continuity mistake: When they are running the obstacle course, the amount of hoops in front of the girls changes from five, to two, to five again.
Continuity mistake: When Scary Spice throws a pillow at Ginger. The pillow is bright purple, but when the shot is on Ginger, the pillow is bright orange.
Continuity mistake: At the end, just after they finish singing, and are all posing, watch Posh Spice, she changes position with every camera angle.
Revealing mistake: Wait until the end of the bonus footage of the Spice Girls' live performance of "Mama". At the very end of the song, the music and voices fade out. Sporty appears to throw her body and soul into one of the lyrics, even though the lyric is barely audible because of the fadeout. It actually looks pretty funny.
Other mistake: When the girls are chatting on a blanket outside the "haunted" castle, you can see Geri discreetly mouthing other people's lines, particularly Emma's.
Continuity mistake: When the girls are walking to the hoops in the obstacle course. Watch Ginger Spice's hand, at first there is nothing in it, then she sings into a walkie talkie that has magically appeared in her hand, the next shot it is gone, then it is back and then gone again.
Continuity mistake: When the Spice Girls are kissing Elton John, from the view facing his back you can see lipstick on his left cheek but when the view changes, it is not there.
Continuity mistake: When they are all gathered in bed, as Baby says, "A big, very old, haunted, big, old house.", Posh puts her hand behind Emma. In the next shot, she has it in front of her, then it's behind Baby again. This keeps happening over and over.
