I rely a lot on Wikipedia and the IMDb, but I'm not unaware of their shortcomings. The problem is that just about anybody can go in to the system and edit their listings.
So this one from the IMDb bugs me. There was an episode of 'MacMillan & Wife' called "Requiem For A Bride". (The type of title you expect to hear "A Quinn Martin Production" after it.) In one scene, Commissioner MacMillan arrives at an apartment complex to find an assault victim being comforted by a guy who could be the building's super.
The IMDb says he's just a resident of the building. But that's not what I have a problem with:
No way is that Buddy Hackett! But if they wanted to hire somebody to play Buddy Hackett's brother back when he was still with us, this would be the guy I'd hire.
Whoever this actor is, I hope someday he gets the proper acknowledgement.....
