Film Career Killer and Mystery Photo
Valerie Bertinelli mentions the film once in her autobiography Losing It: And Gaining My Life Back One Pound at a Time:
"Looking back, I was more ambitious than I remember or want to admit. Soon after my birthday, I jumped into the picture C.H.O.M.P.S., a caper comedy about a guy who invents a crime-stopping robot dog. I read the script and told Tami I had to have that part. I got it in my unsophisticated eighteen-year-old brain that it was going to be a huge movie and push me into a feature career. But come on, C.H.O.M.P.S.? All I want to say about it now is that it wasn't Norma Rae."
In fact, Bertinelli would only do two other (forgotten) feature films in her entire career after C.H.O.M.P.S., and director Don Chaffey (who had directed Jason and the Argonauts, One Million Years B.C., and Pete's Dragon) would never work in film again after directing C.H.O.M.P.S.
And here's a photo of Joseph Barbera purportedly holding C.H.O.M.P.S. (though this is obviously NOT the dog from the film)!
