I watched Brothers Bloom over the weekend. As Stephen and Bang Bang took Bloom to New Jersey to the Ludicrous Mansion in order to show Bloom the next/last big con, after they watch Penelope crash the Lamborghini, they walk down to Stephen's car and Bloom says:
Is this a '78 Caddy? Hm. Controversial choice."
Why was a '78 Cadillac a controversial choice?
