I looked on his IMDb page to see the last thing he'd been in...
He did a voice for "Yo Gabba Gabba" in 2015.
Yo Gabba Gabba is one of Boog's all time favorite shows.
So that's Gene Wilder coming full circle from making me smile in the 80's to making Boog smile in 2016. That's a lot of smiling children over those years. I get some peace from that.
