As it was, I donīt think a SPANIARD, reading a script and emulating the character in a British movie who was wearing a disguise meant to invoke a British historical reference... was going to get across whatever point the group was trying to make. As I recall, that movie was something of a flop here in Mexico, and I don't know how many people would have gotten the reference to it anyway.
The guy (or Guy?) speaking in a Castillian accent alone makes it appear like just another foreign intervention into Mexican affairs by outsiders.
