Here's episode 4 of "Garth Marenghi's Darkplace", titled "The Apes of Wrath". It's a direct Planet of the Apes themed episode, and it's awesome. An easy 24 pts for anyone interested.
Funny skit - liked the chimp girl. Actually the funniest bit was in the opening credits around three minutes: "Music by Stig Baasvik based on melodies originally whistled by Garth Marenghi." How's the other five episodes?
Tho it eventually gained a cult following, the initial ratings for Darkplace were terrible, so Channel 4 didn't renew. Matthew Holness & Ricahrd Ayode appear in a spin off 'Man to Man with Dean Lerner' that had one series back in 2006.
If you've not already had the pleasure, there's a dvd commentary on all 6 original Darkplace eps where the actors commentate in character - Sanchez is getting wasted throughout. I'd highly rec seeking it out
