Brillant timing comedically, seriously underrated dramatic actor, and the constant professional he definitely worked hard and earned his spot in the entertainment history since his career spanned decades, appeared in every movie genre, and his T.V. work.

Outstanding  body of work, you sir will be greatly missed

The day William Shatner goes, will be a massively sad day for me. I grew up with Star Trek and 'The Shat' was one of my boyhood heroes.  I hope he has at least another 20 years left in him.

*  Leslie Neilsen was a brilliant actor who could do straight as well as comedic roles; horror and action. His performance in  Creepshow ((segment "Something To Tide You Over") is of my favs.  But don't forget his appearance in Columbo.

RIP.

But the funniest memory I have of Nielsen is seeing him on a late night talk show (David Letterman, Carson, one of the two) and the host made mention of Nielsen's tendency to pull practical jokes on his movie sets.  Nielsen then produced some little gizmo that made fart noises, said he'd had it for years, and had embarrassed more than a couple people with it.  For the duration of the show (I haven't watched a late show in forever, but at the time guests tended to stay for the whole show rather than just do their segment and leave) each new guest was given the fart noise treatment.  I remember there was some author pimping his book and at the most serious parts of his interview you'd hear "fffffffrrrrrrrrrrrrrt." 

That's all it took.  I became a lifelong fan on the spot.

He'll be missed.

I was just watching Naked Gun on cable for the first time in ages the other day.
