And then fast-forward to 2022, the [[Film/SonicTheHedgehog22022 sequel]] to the [[Film/SonicTheHedgehog2020 2020 live-action Sonic film]] would feature the Master Emerald, which is portrayed as small enough to fit in one hand.

The most prominent example being 2019 version of ''Series/SwampThing'' which was axed by Creator/DCUniverse only after showing ''one episode''.
