The blonde in the T-bird (Suzanne Sommers) in “American Grafitti”.
And M too. How did I forget M. :smack:
A couple from Family Guy
Greased Up Deaf Guy
Giant Chicken
In The Good, The Bad, and the Ugly Tuco calls him Blondie. In For A Few Dollars More, IMDB says his name was Monco.
Red Dwarf’s Cat.
The Waitress from It’s Always Sunny in Philadelphia.
Drat, beaten to one of the ones I recalled from Peanuts. The other one would be Pig-Pen.
And to forestall a cite to the contrary, the name Heather for the Little Red-Haired Girl (as well as her very visage) is non-canon, existing only in the animated specials, not in the comic itself.
Nope, that would be Dwayne Johnson acting as The Rock, acting as his character in The Scorpion King.
Makes perfect sense to me.
As for M - we do know that either her given, maiden or surname starts with an M 
In the 1939 film THE WIZARD OF OZ, the wizard is not named but in the L. Frank Baum books he is Oscar Zoroaster Pardrig Isaac Norman Henkel Emmanuel Ambrose Diggs.
The Tin Woodsman had the name Nick Chopper
The Scarecrow and the Cowardly Lion never got their own names.
Baum did not name the Wicked Witch of the West but the later book and Musical WICKED names her Elphaba.
Comic Book Guy does have a name:
In addition, Tolkien indexer Foster has suggested a possible name for one of the Nazgul (although Tolkien says it’s not recorded). The Wiki entry goes on to claim:

Q and M are named, both in the books and the movies. Q is Major Boothroyd, and M is Sir Miles Messervy.
Macbeth’s first name is probably Macbeth – he might not have any other name. Presumably Lady Macbeth had a name before marriage, but we don’t know what it was.
I haven’t read all the books, but in which movies are they named?
(And I somehow doubt that’s M’s name in the latest movies )
Yes, as I noted. But I think you haven’t read the OP. These names may be available if you search for them. But they are not well known to the general public. Everyone knows who Q is. Not many people know who Major Boothroyd is.
Chef from South Park.
(Yes, he’s got a name too. Anyone remember it without looking it up? I certainly don’t. He’s almost always just called Chef. )
Which is why the OP noted that:
“Yes, I know that the writers eventually gave this character a real name. But if you asked the random person on the street who ‘Jeff Albertson’ is, they’d stare blankly; whereas if you asked who ‘Comic Book Guy’ is, a large percentage of folks would know he’s a Simpsons character.”
Yup. Macbeth was his first name. His last name, historically, was mac Findlaích. If one is also going by history, Lady Macbeth’s first name was Gruoch.
But everyone knows Shakespeare played fast and loose with history.
Macbeth being a historical character we know their full names, even if not given in the play. He was Mac Bethad mac Findlaích, she was Gruoch ingen Boite
Edit: beaten to the punch.
I saw a Spanish movie El Aura (The Aura) about a shy taxidermist who fantasizes about committing a perfect crime (like a bank robbery or heist) who, quite by accident end up involved in a heist. When we saw the movie, we noticed that no one ever called him by name. Everyone was so disdainful that no one bothered to show him even that courtesy. In the credits he was listed as The Taxidermist.
On IMDB, they say his name is Esteban Espinosa, but neither of us remember him giving any name and if he did it was likely an alias (otherwise, why wouldn’t if have been in the credits at the end of the movie?)
Several characters from Catch-22 spring to mind for me, namely Major ----- De Coverley, The Soldier In White, and Hungry Joe.
I saw Luke a few weeks back, and it seems to me that one of the guards addressed him by name. I may be wrong.
Did the title character of that odd TV series The Prisoner have a name, or was he always Number Six (Number Two or One in the last scene)?
