A blogger in Santa Barbara has an interesting take here:
"The names of the title characters are assigned rather strangely. Whereas the elder Bloom Brother gets a regular first name, the younger one is only addressed as Bloom. Unless his name is Bloom Bloom — which wouldn’t be inappropriate, given the handful of ways the film reminded me of Pushing Daisies — his first name is simply never uttered and not listed in the credits. It’s not unheard of that this would be the case. (For example, the “I” in Withnail and I is never named in the film.) But if Bloom is actually Adrien Brody’s character’s first name, then this film’s brother-brother pair would be the only one besides the Mario Bros. to have a first name arbitrarily applied to both in the way a last name usually would. An online contest was apparently held to give the younger Bloom a first name — or at least so says this article, which, curiously, was written by someone named Dan Bloom — but there’s no indication of what the results of that contest were."
AND THAT BLOGGER ABOVE ALSO NOTED: AND HE MIGHT NOT BE CORRECT, AS MAXFROST IS TO POST TOMORROW IN CORRECTING THE COMMENT:
''Speaking of names, the pairing of the names Bloom and Penelope made me think of the marrieds in Joyce’s Ulysses, even if the female half of that pair is actually named Molly. The book’s final chapter — Molly’s chapter, arguably — is titled “Penelope.”''http://kidicarus222.blogspot.com/
