The remaining son, Nemo (Alexander Gould), is also handicapped by having one fin smaller than the other, which Marlin refers to in doting PC terms as his “special fin”. Marlin’s over-protectiveness fosters a rebellious streak in Nemo, who wilfully wanders off into the big ocean on his first day at school and is promptly caught in a diver’s net. Transported to an aquarium in a Sydney dentist’s surgery, Nemo resigns himself to captivity until his fellow inmates
concoct an escape plan.
