The Lorax (2012)

Continuity mistake: When the Once-ler is drifting down the river in his bed, he puts his foot in the water, which makes the bed turn. When he puts his foot back onto the bed, it is dry and so is the bed sheet.

Continuity mistake: When Ted visits the Once-ler for the second time and dives to the ground to avoid being launched by the sledgehammer as happened the first time, he stands up and his goggles are around his neck but hanging behind him. The scene then switches to the Once-ler and then back to Ted, and his goggles are still around his neck but now hanging in front of him.

Continuity mistake: In the scene where Ted's mom is distracting one of O'Hare's men by driving away with "Ted" in the backseat, the Ted dummy disappears and reappears between shots.

Trivia: When Ted opens a drawer looking for a nail for the Once-ler, a Minion figurine (from Despicable Me) is shown in the drawer.

Trivia: The characters of Ted and Audrey are named after Dr. Seuss (whose real name was Theodor Seuss Geisel) and his second wife Audrey Geisel.

Trivia: The song 'How Bad can I be?' is perfectly synced with YouTube's 5-second skip with the left and right arrow keys. Watch the song on YouTube and press the right arrow key to skip perfectly from 'bad' to 'bad'.

Once-ler: Whoa, whoa, whoa! You wouldn't hit a woman.
The Lorax: Hoo! That's a woman?

Once-ler: So you want to know what happened to the trees? I didn't think anybody still cared!
Ted: Well, that's me! The guy who still cares!

Ted: The last seed?
Once-ler: It's not about what it is. It's about what it can become.
