I preferred the Grammer-Quinn movie but I thought Daniels did a fairly good job.
I still don't think Hollywood has done the definitive George Washington, though, and am still waiting for it.
My personal nomination would be David Morse's unbelievably understated portrayal of Washington in the "John Adams" mini-series (a MUST-HAVE for your collection). Paul Giamatti's Adams was a tour-de-force; Morse played the perfect foil, even with limited screen time. He exuded strength, determination, and humility....as well as righteous anger at times. I thought he was brilliant.
