Apart from playing Doctor Octopus well, Alfred Molina also has to learn to get along with the four mechanical tentacles. The tentacles of Dr. Octopus are exquisite and delicate, but this also means that Molina has to adjust all his movements and postures as Dr. Octopus. Molina, Remy, and the puppeteers and designers of Edge FX software company rehearsed for several months together, and finally researched out the complicated trajectory of the mechanical antennae.
The weight of the tentacles of Dr. Octopus is between 75 pounds and 100 pounds, depending on the plot requirements. These tentacles are multi-articulated and can reach 13 feet when fully extended. Each antenna is composed of 76 parts. The main joints of the tentacles are all done by hand, and they also need to be colored by hand. If all the tentacles are connected end to end, it will exceed the height of 20 stories.
