And that’s not all of it. Forbidden Planet needs fix-ups (apart from the-usual-suspects releases).
Like 2001: A Space Odyssey, Forbidden Planet special effects also shows it’s “frayed edges”. For example, in this shot (Blu-ray), it is clear that the actors are walking outdoors on an overcast day (also see reflections from the rain puddles?) with a matte painting all around them [TOP picture]. Why does it look phony? First, the walk-way colors don’t match. Even when that is corrected (the matte painting matched to the live action) [MIDDLE picture], still visible are street/parking-lot construction joins (or whatever) going off in wrong directions. Erasing those biggest eye-distractions allows the shot to look more natural [BOTTOM picture].
No global color correction was considered in the above (which it needs anyway). Without any on-the-set or behind-the-scenes sources, here’s a suggested color correction . .
