Continuity mistake: This can only be seen for a few frames, so slow motion may be needed. Tommy reveals himself as the White Ranger by unclipping his helmet; however, his ponytail is already visible. Tommy's hair should have been inside his suit/helmet if he had just unclipped it. From behind shots, it is tucked in.
Other mistake: The Tigerzord has various orbs behind the White Ranger, that give the Tigerzord various abilities. The only one we ever see used is the one for a Fireball. For the rest of the series, this orb disappears and reappears, whether the Fireball has been used or not.
