Thanks to all of our readers who responded to yesterday's post and the question:  what films did Chuck Jones act in (theatrical & TV), other than Joe Dante's 1984 "Gremlins"?  Here's the complete list:

1.  The Pogo Birthday Special (TV special,) 1969: voice actor, Porky Pine, Bun Rab, Basil the Butterfly

2.  The Phantom Tollbooth (feature film,) 1970:  man sitting on trolley next to Milo (Butch Patrick)

3.  Horton Hears a Who! (TV special,) 1970: voice actor, Junyer Kangaroo

4.  The Curiosity Shop (TV show,) 1971

5.  Gremlins (Feature film,) 1984: man in bar

6.  Innerspace (Feature film,) 1987: grocery store customer

You may see that IMDB.com lists a role in the feature film "The Arrogant" from 1987 that they say Chuck Jones appeared in, but that is not confirmed by the Jones family.  

Tock, Milo and Humbug from the 1970 feature film, "The Phantom Tollbooth," directed by Chuck Jones.
