Thanks to Google Alerts, I just found out that someone posted a tribute to my father on YouTube, "Character Actors: Lionel Stander," a mishmash of scenes from the 1976 disaster pic The Cassandra Crossing. Dad plays a Swiss (!) train conductor named Max (also his character name in "Once Upon a Time in the West" and "Hart to Hart," and maybe others), with no attempt made to disguise or explain his New York accent.
The movie, with a screenplay cowritten by Tom Mankiewicz, is so God-awful that it's comical; "Murder on the Orient Express" it ain't. Even more fun is to be had in spotting the all-star cast: Richard Harris and Sophia Loren as a crime-solving couple named Jonathan and Jennifer (more shades of "Hart to Hart," some episodes of which were directed and written by...Tom Mankiewicz), OJ Simpson, Ava Gardner, Martin Sheen, Lee Strasberg and Burt Lancaster.
Duh...I never thought to search YouTube for the Old Man. Turns out he has five pages of vidclips (a distressing number of which are from "Hart to Hart"). Here's one that's intentionally funny, the trailer for Polanski's "Cul-de-Sac":
