yes it is, the guy was a comic genius. Loved the Naked Gun, "that's no way for a man to die!" "You're right, getting caught in the gears of a combine, that's how I want to go!" and who can forget, talking to Pricilla Presley who is standing on a step ladder, "Great looking Beaver!"
The "Naked Gun" series and "Airplane" are some of the funniest movies ever made because of Leslie Nielson. He had a very unique deadpan way of delivering a comic line.
