BLADE RUNNER

i had never heard of Idris Elba before i saw Prometheus but his character was rather memorable and like-able. i just finished watching his television series LUTHER on netflix and i think he would make a great "Deckard like" character in the next installment of Blade Runner. any thoughts ? (if you havent seen Luther i highly recommend it. its a police drama which does have a few of the cliches of that genre but is actually quite good in my opinion and Idris Elba is excellent in it!)
