Did You Know?


One of the rare, if not the unique, episode where Tara drives Steed's car; the antique Rolls Royce. See more »


In many episodes Steed's bowler is used by him or someone else to hit someone on the head, with a sound effect revealing it to be metal, the person invariably knocked out.

In this episode Steed is hit on the head whilst wearing his bowler, and it affords him no protection at all. See more »


Haller: Has a steampipe broken or something?
John Steed: Eh? Oh, that's fog. That's fog, Mr. Haller. We still lead the world in that department.

Nigel Green and Guy Rolfe
13 May 2011 | by kevinolzakSee all my reviews

"Fog," as the title implies, is drenched with misty atmosphere, another splendid Jeremy Burnham script effectively rendered by director John Hough. Cobblestone streets, flower sellers, organ grinders, and a man specializing in knife sharpening, all evoking 19th century London as a modern day 'Jack the Ripper' stalks the members of a disarmament conference. The first half sets up the murders, while the second has The Avengers investigating an exclusive club devoted to the legendary Gaslight Ghoul (the entire episode takes place in one fog shrouded night). Guy Rolfe had appeared in many shows on both sides of the Atlantic (Karloff's THRILLER), and played the title role in 1961's "Mr. Sardonicus," while Nigel Green, previously seen in a smaller part in "The Winged Avenger," tops the guest cast as the club president, who also happens to be an expert surgeon. Also featuring Paul Whitsun-Jones ("Man with Two Shadows," "The Wringer," "Room Without a View"), Norman Chappell ("Dance with Death," "Dead of Winter," "The Gilded Cage," "Dial a Deadly Number," "Murdersville"), David Lodge ("Epic"), John Garrie ("The Winged Avenger"), Arnold Diamond ("Who's Who???"), Frank Sieman ("Six Hands Across a Table"), and William Lyon Brown ("Death's Door").
