Props to Oldman bc he helped design the character:
Because Dracula's scenes did not start filming until very late into the production, Oldman had plenty of downtime to come up with additional ideas for his character. According to Coppola, "He'd [Oldman] get together with the makeup designer Greg Cannom and, before I knew it, we were going to have not just one monster but five monsters in the film."
