Man, I’m starting to regret this choice. I didn’t think it was easy, but I thought it would at least be known among this crowd.
It probably is known, it’s just not coming readily to mind. Hang on, we’re not done yet.
It’s funny how different obvious looks from the other side - I didn’t expect to go to 19 questions with two people who each had something named after them commonly denoted by the chosen letter itself. I fully expect to kick myself when this round is done.

I’ve got a hint or two I’m willing to drop, but I’ll wait on that. 
IQs:
- Are you a summoner in League of Legends?
- Were you a panelist on What’s My Line?
- Were you a banker whose biggest account was a bunch of hillbillies?
2 more DQs, and I’m not Mr. Drysdale.
My son-in-law plays League of Legends: the character is Draelin.
Dorothy Kilgallen was the panelist.
Just stocking up my DQ’s for the endgame. Back to serious ponderment.
Huh. I wonder if I can claim some kind of copyright infringement. I’ve been using this name on the interwebs for at least seventeen years now. 
IQ: Do you reside in a castle which has a large, grail-shaped beacon?
The only name I’m coming up with from Castle Anthrax is Zoot, which does not start with D, so DQ.
I was thinking of Zoot’s sister, Dingo. I’ll need to take some pondering time before I do anything else.
Cashing in a DQ; hope this gets us somewhere…

[Table Talk] Just because the film is in English, doesn’t mean it was a British film. Do you think it’s worth asking if this is an American made film, just so I stop mentally running through all the Monty Python and Ealing comedies? It could well be a Peter Sellars film, with those dates, too…[/Table Talk]

[Table Talk] There’s Woody Allen’s comedies and Mel Brooks’s comedies as well. Was there a British female in It’s a Mad Mad Mad Mad World? Would the Beatles’ movies be considered comedies? Think think think… [Table Talk]
There was not a British female in It’s a Mad Mad Mad Mad World - just the gap-toothed Terry-Thomas.
