"But seriously, Watch for fire..fire bad."
Frank, to Mavis
- Due to various trademark and copyright issues with Universal Studios, Sony had to follow certain rules about Frankenstein's looks. "Early on, we got a list of criteria that we needed to follow, things that we could not do because they were trademarked," says producer Michelle Murdocca. According to the list, "'Frankenstein' can't be green... and he can't have electrodes on his neck. We tried bolts on his temples. We tried light bulbs on his neck. Nothing would get by," Murdocca says, "So we went without bolts and we made him blue."
- Frankenstein's fear of fire is a reference to the 1931 Universal Studios film Frankenstein, where the same character is extremely fearful of fire, who ultimately is defeated in a burning windmill.
