Onward

One of the most iconic monsters in Dungeons & Dragons is the gelatinous cube. Imagined by creator E. Gary Gygax himself in the very first edition of Dungeons & Dragons in 1974, the gelatinous cube is a staple foe that players encounter early on in their adventuring. (It has an entry-level challenge rating of "2" in the current version of D&D. That's low.) The cube moves slowly but can be very dangerous once it gets close, as it absorbs victims and slowly digests them while they float helplessly inside.

When The Manticore is telling Laurel about the curse, she tears off her sleeves to reveal expository tattoos on her arms. However, when Laurel initially asks about the curse, The Manticore's left sleeve is already seen to be torn off as the tattoo is already visible.

A nod to a role-playing classic in the closing credits: "Special thanks to the D&D team at Wizards of the Coast for use of The Beholder and The Gelatinous Cube"

The movie is also presented in a 3D version, the IMAX-Enhanced version and the 4DX-Enhanced version.
