I happened to be watching an episode of the 80's show Cosmos which was hosted by Carl Sagan. Sitting and listening to his voice, I was puzzled, thinking "Who's voice does this sound like?". I came to the conclusion he sounded just like Agent Smith from The Matrix.
My question is, Did Hugo Weaving copy the voice mannerisms from Carl Sagan for the part of Agent Smith? Is there any evidence in the media or through interview why Weaving portrayed Smith like this? It's definitely not his normal speech pattern.
NOTE: I know it is hard to prove a negative. If someone has any information as to why Weaving played the part this way would be sufficient for an answer.
For reference, here are two clips, one of Carl Sagan describing the 4th dimension and one of Agent Smith while interrogating Morpheus.
