Regarding Easter Eggs on a Km DVD, it'd be nice (although probably impossible due to legal reasons) to have, say, a second hidden 'play episode' button that shows its old Children's ITV link.

The Chromakey Experiment footage would be an excellent Easter Egg, too, imo.

Two instances of things being 'added on' to the episodes in post-production happened - in Series 4 a series of letters appeared throughout the rooms, and viewers were invited to spell out a word with the letters which appeared.

Also in Series 5, a scroll appeared, bafflingly, mid-quest, unfurling to read "Another name for Hordriss?" Again, this was a CiTV competition. The answer was 'Harris'.

However, if you're looking for secrets in Knightmare, you need look for bloopers, in my view - just check out the staircase in the Castle of Doom, Series 4 - there's a hazard warning sign on the wall! In fact, most Eye Shield sequences, particularly in the early series' where they weren't computerised at all, had a few of these in...

Is it?  I always thought it was a rather british tradition.

I thought it might be why the poster did not know the reference (I assumed he was british) but Im obviously wrong then, it has been a few years

This is a more common tradition in america though.

Knightmare sometimes had puzzles for viewers, like finding the letters to spell a word, you would send in the answer and maybe win some prize if yours was the first to be drawn from the postbag. Can't remember any specific examples though.

The players didn't seem to see these special letters though, I assume they were put on afterwards.
