Bob Newhart was the kindest most hilarious man.
He asked me to make a documentary about his friendship with Don Rickles.
I was so lucky to get to spend that time with my hero.

His brilliant comedy and gentle spirit made everyone he encountered so happy.
Even his silence was funny.
His reaction said everything the audience was thinking.
I will miss his kindness and his humor… and his love for a great comedy bit.
I feel so lucky that I got to share the screen with such a legend.
What a dream it was to witness the genius that was Bob Newhart.
He was classy, kind, generous, and absolutely hilarious, Cuoco remembered.
Every take every time.
I will never forget you Bob!
Thank you for making our dreams come true!
You will be missed, Curtis captioned.
