This breakthrough lands Clive and Elsa presumably writer-director Vincenzo Natali is deliberately referencing Elsa Lanchester and Colin Clive, co-stars of The Bride of Frankenstein on the cover of Wired magazine and earns them the gratitude of some nefarious pharmaceutical corporation with plans to harvest Fred and Ginger's "proteins."
Movie geeks will recognize that these hipsters (who dress like club bunnies rather than lab rats) are named after Colin Clive and Elsa Lanchester, the mad scientist and his creation in The Bride of Frankenstein.
Clive and Elsa are, of course, a reference to Colin Clive and Elsa Lanchester, who played Dr. Frankenstein and the Bride of Frankenstein in the 1935 masterpiece "The Bride Of Frankenstein," and that obvious joke is also a statement of mission: Natali knows exactly what story he's teling, and he wants to bring Mary Shelly's original concepts into the age where genetic miracles have become almost commonplace.
Adrien Brody - sorry, Oscar winner Adrien Brody - and Sarah Polley are punky biogeneticists Clive and Elsa (apparently named for Colin Clive and Elsa Lanchester , who played the mad scientist and his creation in 1935's "The Bride of Frankenstein").
