Above, Everett Sloane as Capt. Frank Kennelly in CBS radio's "21st Precinct," July 21, 1953. 

Update: This week's photos weren't much of a mystery. I think this is the first time anyone has complained that our guest was "too easy." I figured Everett Sloane wouldn't be much of a challenge, but most people only know him from "Citizen Kane," "Lady From Shanghai" and that wonderful "Twilight Zone" episode, "The Fever,"  where he's chased by a slot machine.

Aug. 7, 1965: Everett Sloane commits suicide.

Just a reminder on how this works: I post the mystery photo on Monday and reveal the answer on Friday … or on Saturday if I have a hard time picking only five pictures; sometimes it's difficult to choose. To keep the mystery photo from getting lost in the other entries, I move it from Monday to Tuesday to Wednesday, etc., adding a photo every day.

I have to approve all comments, so if your guess is posted immediately, that means you're wrong. (And if a wrong guess has already been submitted by someone else, there's no point in submitting it again.) If you're right, you will have to wait until Friday. There's no need to submit your guess five times. Once is enough. The only prize is bragging rights. 

The answer to last week's mystery star: Wallace MacDonald!

Update: Everett Sloane in "On Trial," Dec. 14, 1956.

Nearly everyone recognized our mystery guest. For those who want another try, here's a second picture, heavily retouched by The Times' art department.

Update: Ernie Kovacs and Marie Windsor in "Salted Mine" on the Schlitz Playhouse, March 22, 1959.

And for those people (you know who you are) who complained that this week's mystery guest was too easy, here's another picture that may be at least a bit more challenging.

Update: Everett Sloane in "Massacre at Sand Creek," an episode of "Playhouse 90," July 25, 1957. 

Here's another picture of mystery guest No. 1. Most (but not all) readers have correctly identified him — and many have quoted dialogue from his most famous roles. The picture above is not one of them. Anyone care to guess what it's from?

Update: Ernie Kovacs in "The Jane From Maine," retitled "It Happened to Jane," June 4, 1959.

Here's mystery guest No. 2 — not much mystery here. Any guesses as to the role for which he shaved his head — and what brand of cigar he's got in his pocket?  

Update: OK, I'm running out of weird pictures of Ernie Kovacs. And no, he isn't posing with any brand of cigar you'd expect. Take a good look. 

Update No. 2: These are H. Upmann No. 1 Cuban cigars. Kovacs kept a huge supply of them in his personal humidors and they still turn up for sale, long after his death. At $300 each, if you can find them. (These are sold out).

Update: Everett Sloane, June 8, 1958. This photo was published with a TV listing about "The Strong Man" on "Studio One."  

Today we have two armed and dangerous mystery guests. Here's No. 1. I never realized he had a broken nose.

Update: Paul Picerni with Lynne Carter and Buddy Ebsen in "Honest John." Jan. 30, 1950. The play was written by Ebsen and directed by William Talman — that's right, Hamilton Burger in "Perry Mason," who was married to Carter at the time.  

And who is this mystery gunman?

Everett Sloane in "The Spy," an episode of "Goodyear Theater," Nov. 14, 1958. That is a seriously broken nose. I'm surprised I never noticed it before.
