A lot of the subtlties and Alan's little quirks were picked up by his successor(s) and then passed down through all of the guys who played the part, which is kind of unfortunate for them, and for their fans, because it's impossible for them to be given *all* that much credit. Some of them took more ownership of the adlibs than others, some just used Alan's, almost word for word, but the framework was his and Mendes' creation.
Funny thing: Riedel called Raul a "twerp," who wanted to be Alan Cumming.
