Career Timeline: 1986 - Willow
Moebius is hired by George Lucas to do some extensive design work for Willow(released in 1988). He does quite a bit of character/set design work that never gets used. In some cases, like the piece with the sea monster, Moebius just made the whole scene up from scratch in hopes that they might give it a shot.
I would love a whole book of Moebius’ film design work.
