While not up to the standards(?) of Avalon's other mid 60's romps (Beach Blanket Bingo, et al), the movie still provides a lot of fun. And as usual, Vincent Price as the mad scientist makes it all worthwhile. Though the widescreen presentation is commendable, the production values are cheesy. Take note of the scene where Avalon's red convertible changes from a Plymouth Fury to a Dodge Coronet, then back to the Fury again. Talk about continuity errors! All that aside, it's still a great nostalgia piece.
