If you haven't read it yet, read A Guide For the Perplexed, which is basically him talking about stuff (mostly films) in his own words. But the films become catalysts for his random musings, he can't help but dish out great throwaway lines about the wonders and meaning of existence no matter what he talks about.
It's one of my favorite books on this side of the century.
Somehow I doubt T-Rexes had the intelligence of a crow.
What would lead you to a conclusion one way or another? The Tyrannosaurus seems to be well evolved to a similar hunt/scavenge lifestyle to crows. They likely had a large set of sensory input to process.
